There are few details as important as carpet in your classic Corvette. The fact of the matter is that early C2 carpet doesn’t age well, thanks to the overlapping design that eventually changed in 1965. There aren’t many C2 Corvettes out there sporting original carpet, and in the case of this 1964 Corvette coupe, the original carpet was replaced 30 years ago. The original replacement carpet was sun-faded and the adhesive started coming loose a couple of years ago. It was really hurting the appearance of the car, and we finally decided to overhaul the interior, starting with fresh carpet from Paragon Corvette Reproductions.

The Paragon carpet kit is sourced from Al Knoch, and it’s a complete kit for 1963 and 1964 Corvette coupes. This kit fits coupes with or without the rear blower motor. Our project car happens to be a late 1964 coupe that has the blower motor. Along with the carpet kit, it’s a good idea to replace the quarter-panel trim pieces as well as the plastic rear window garnish molding and rear window vinyl. These additional parts will add up to a couple of hundred dollars but they are essential in giving your Corvette the proper interior makeover. You’ll also need some heavy-duty scissors, a carpet knife and at least two 19-ounce cans of 3M Super Trim Adhesive. Some folks prefer to use brush-on adhesive, but the aerosol type works fine.

Most importantly, you’ll need a healthy dose of patience for this project, as it is certainly tedious and time consuming. Keep in mind that you’re installing 19 pieces of carpet in a very small interior, and they all require a special order of installation. Most pieces require trimming for proper fitment, but the custom-tailored appearance is worth the hours you’ll spend test-fitting and trimming. The end result of the trim, glue, repeat routine is a beautifully restored interior that looks better than new. See how we tackled this project, and take note of some of the tips and tricks to make your C2 coupe carpet installation quicker and easier.

01. The carpet in our 1964 Corvette coupe was looking rough on all accounts. The black carpet had faded badly and many pieces had lost adhesion after 30-plus years in the car.

02. The unfortunate part about C2 carpet is that most of it glues into place. That means as years go by, the elements will take its toll on the adhesive and the carpet itself, as evidenced by the buckled carpet over the driver-side wheelwell. Also notice the adjoining interior panels, which need to be replaced.

03. Removing the carpet is a fairly quick process. In most cases, the carpet isn’t stuck to the interior panels hard enough to leave behind a mess. You’ll be removing 19 pieces of carpet, so you may benefit from keeping the carpet together in various sections to help with the reassembly process.

04. The seats are removed, as is the console and center armrest. You’ll also need to remove the kick panels, the throttle pedal and the door sill plates.

A1 Knoch Carpet Set 6/41

05. Paragon Corvette Reproductions provided the Al Knoch carpet set, which is specific for 1963 and 1964 Corvettes. It’s important to take all of the contents out of the box and lay them out in the sun to let them straighten out. This also allows you to do a quick inventory of the pieces.

Jm Super Trim Adhesive 7/41

06. We started with the smallest pieces to get an idea of the setup time and the results of the 3M Super Trim Adhesive. These 19-ounce cans go a long way, and two cans should get you through the entire job. After scraping the leftover foam and adhesive from the kick panels, we spray the panel and the backside of the new carpet.

Kick Panel 8/41

07. The cover for the rear storage area was our next subject, as it was also a straightforward process, like the kick panels. The old carpet was barely hanging on, and there was a ton of leftover foam and adhesive on the panel. We scraped it clean and sprayed adhesive on the panel, allowing it to sit a couple of minutes to tack up.

Rear Storage Cover 9/41

08. There are a couple of ways to tackle the rear storage cover. The method shown here can work, but we found it easiest to line up the carpet with the panel by flipping the carpet over and pressing the panel into place. The long, straight side of the carpet will leave about 1/8-inch of the board exposed, and it will be hidden when the panel is in place.

Carpet Tab Hole 10/41

09. Using a razor knife, we cut the carpet around the pull tab hole in the storage compartment cover. We reused the original chrome bezel, bending the three tabs around the panel to secure it. These tabs can easily break, but new pull tab bezels are available.

Divider Panel 11/41

10. After some studying, we decided the first piece of carpet to install in the car is the divider panel behind the seats. Since we’ll be climbing in and out of the car often, it’s best to leave the front portion of carpet for last. The divider panel carpet is trimmed to fit and glued into place.

1964 Corvette Wall Carpet 12/41

11. The back wall carpet requires trimming along the bottom edge for an exact fit. We used scissors to make long cuts and used a carpet knife for some of the more intricate cuts.

12. Get ready to climb in and out of the back of your C2 coupe dozens of times. Trim a little at a time until it’s to your liking and then spray the carpet underlayment as well as the backside of the new carpet with adhesive. On a warm day, the adhesive sets up quickly, especially after it has made contact with the adjoining panel.

1964 Corvette Wheelwell Carpet 14/41

13. An important step is to mock up the wheelwell carpet. We started with the passenger side, laying the three pieces of carpet into place and figuring out how they are oriented. The piece closest to the floor goes in first and requires trimming around the bottom edge, while the other two pieces require minimal trimming.

14. Masking tape and paper can be used to prevent the adhesive from getting on the new carpet that we’ve already installed. You’ll notice that tape doesn’t stick very well, so we eventually used a scrap piece of carpet as a guide to keep the glue where we wanted it.

Fiberglass Wheelwell 16/41

15. We trimmed the carpet until the vinyl seam aligned with the curve of the fiberglass wheelwell. Then, we installed the intermediate piece of carpet, which overlaps the bottom piece. At the rear, the intermediate wheelwell carpet seam is split, allowing the lower piece to lap over. This orientation is why it’s important to mock it up before gluing.

1964 Corvette Upper Carpet 17/41

16. Finally, we can install the upper piece of carpet, which overlaps the intermediate piece, and tucks behind the lower piece at the rear. After fitment and minimal trimming, we glue the upper carpet into place.

1964 Corvette Interior Panel 18/41

17. We also ordered new interior quarter-panel trim from Paragon, which are factory-style cardboard pieces, wrapped in vinyl material. These pieces are a little tricky to install, thanks to the thickness of the new carpet. The panels slide in behind a piece of channel on the doorjamb and they are held in place with two screws.

1964 Corvette Driver Side Wheelwell 19/41

18. This is where it gets interesting. According to our research, the driver-side wheelwell of 1963 and early 1964 Corvettes was essentially a mirror image of the passenger side. However, late 1964 (and 1965) coupes featured a rear blower motor, which spaced the carpet out farther.

Wheelwell Carpet 1964 Corvette 20/41

19. Here, we’re cutting the bottom edge of the lower piece of wheelwell carpet. It’s best to trim the carpet to have 1/8-inch gap at the bottom to allow the main floor carpet to tuck in beneath it.

Paragon Carpet Kit 21/41

20. The Paragon carpet kit comes with pieces to accommodate both styles of rear wheelwells so you’ll end up with one extra piece. Our first step is to mock up the cardboard cover for the blower motor, and then mock up the lower section of carpet.

1964 Corvette Blower Motor 22/41

21. Since our car has the blower motor, we needed to trim the lower section to fit beneath the cardboard cover. This is how we did it, and the fitment was spot on. After some trimming along the bottom edge, the lower piece is ready for glue.

22. Another step that is necessary for blower motor cars is to cut the threads that connect the two pieces of intermediate wheelwell carpet on the driver’s side. Completely separate the two pieces and discard the upper piece. You will only use the lower portion of this two-piece section.

1964 Corvette Carpet Install Overlap 24/41

23. The intermediate piece overlaps the lower carpet section and tucks in behind the cardboard blower motor cover. Notice the small “cage” that fits between the cardboard panel and the back wall carpet. This is where the rear vent allows air to circulate out of the wheelwell area.

1964 Corvette Wheelwell Carpet 25/41

24. You’ll choose between two options for the upper driver-side wheelwell carpet. For 1963 and early 1964 coupes you’ll use carpet that tucks in behind the lower piece (like the passenger side). On late 1964 coupes with the blower motor, the kit uses a specific piece of carpet that has a vinyl seam around the edge. Factory restorations use exposed screws that go through the carpet and hold the cardboard in place. We installed the cover and glued the carpet to the cover without the exposed screws.

1964 Corvette Differential Hump 26/41

25. Piece #12 (but who’s keeping count?) is the small section to cover the rear differential hump. This piece glues into place with no trimming necessary.

26. The main rear floor carpet requires trimming on the edge that folds down into the storage compartment area. Without trimming this area, the cover for the storage compartment will not fit correctly.

1964 Chevrolet Corvette Rear Floor Section 28/41

27. The rear floor section has a vinyl seam around the sides and back so it is designed to go in last. We left 1/8-inch gap in the lower wheelwell carpet sections, allowing the vinyl seam to neatly tuck under the edge. After it is carefully fit into place, we glue it and press it down.

1964 Chevrolet Corvette Quarter Panel Trim 29/41

28. Finishing off the rear carpet section is the driver-side quarter-panel trim. The panel has two small S-clips that slide into the upper “halo” interior panel. Then, the front edge slides into the channel in the doorjamb and two screws hold it into place.

1964 Chevrolet Corvette Rocker Panel Carpet 30/41

29. After laying the front sections of carpet into place for mock-up, we can see what needs to be trimmed. Our first piece is the rocker panel carpet, which needs slight trimming around the front edge of the doorsill plate and doorjamb.

1964 Chevrolet Corvette Rocker Panel Section 31/41

30. The rocker panel section has very little wiggle room for front-to-rear fitment. The vinyl seam is designed to turn the corner at the rear of the doorjamb, but you must also consider the overlap of the kick panel and the main floor carpeting when installing this piece.

1964 Corvette Carpet Install 32/41

31. After the rocker panel carpet is glued into place, we glue the transmission tunnel carpet for the passenger side. The front sections of carpet require less trimming than the rear section.

1964 Corvette Floor Portion Carpet 33/41

32. The main floor portion of carpet can now go in the passenger side. This piece has a vinyl seam around the sides and front, so it goes in last and requires no trimming for proper fitment.

1964 Corvette Passenger Side Carpet 34/41

33. As we’re nearing the end of the passenger side front section, we can install the doorsill plates, which overlap the rocker panel carpet and hold it in place. The kick panels are also installed.

1964 Corvette Carpet Install Bolts 35/41

34. Using a carpet knife, we cut around the front boltholes and rear channels for the seats. After test-fitting the seats, you may trim the strips where the seat frames rest against the carpet. You can also allow the seats to rest on the new carpet, but you may need to find longer seat bolts to fit.

1964 Corvette Transmission Tunnel Carpet 36/41

35. An area of concern on the transmission tunnel carpet pieces is console fitment. Be sure to trim the carpet around the console mounting tabs, but be careful not to notch the carpet too aggressively as the console does not slide very far below these tabs.

1964 Corvette Carpet Driver Side 37/41

36. The main floor carpet on the driver side does not come with a hole for the dimmer switch, but it does come with a new grommet. After test-fitting the main floor carpet on the driver side about a dozen times, we found the appropriate place to cut the hole and install the grommet.

1964 Corvette Driver Side Carpet 38/41

37. One of the challenging aspects of the driver-side main floor carpet is the fact that the carpet must be aligned perfectly with the throttle pedal bolts as well as the transmission tunnel carpet section. We use two screwdrivers as guides for the pedal boltholes.

1964 Corvette Bolt Seats 39/41

38. The last cuts are necessary to bolt the seats belts into place. Never use a drill to make the boltholes in carpet—the bit can grab a thread and make a mess of your new carpet. Always use a knife to cut the holes, even if it’s more time consuming.

C2 Carpet Kit 40/41

39. We lost track of the time it took to install our early C2 carpet kit from Paragon, but this is not something that you’d want to tackle on a single weekend. The most important tip we can give you is to take your time with trimming, and you’ll have carpet with a custom-tailored fit and finish.

1964 Corvette Interior Carpet Install 41/41

40. With the seats installed and the console re-assembled, our 1964 Corvette coupe looks like a totally different car. While time consuming to install properly, the carpet kit and related interior panels from Paragon made all the difference in the world.
