Nova Convertible Top - Raising The Roof

Convertible Top Installation Made Easier With New Parts From Year One

Raising The Roof Correct Components
Installing a new convertible top is not a job for everyone. But if you are ambitious, have the necessary tools--and the desire--to tackle the chore then there are a few things you should know. First, get the correct components. Chances are aside from the frame itself, your convertible will need just about everything new. Do as this owner did, call Year One for replacement parts. They had all the items this Deuce required. For the rubber weatherstrips, a call was made to Joe Grom at Chevy II Only.

When the sun's shining it really doesn't matter what shape your classic convertible's top is in. And why should it, since a drop-top is most fun when you're cruising with the breeze in your hair and sunglasses on. But wait until the next time it rains or gets cold out and up goes the top, you're sure to be a little more concerned then. And, you'll be happier-and warmer-if it does its job of sealing out the wind and water.

While this is an obvious sentiment, what's not so obvious is that fixing or replacing a convertible top is not as easy as you might think. First, most older convertibles are sure to have worn out parts other than just the outer material and back window. The mechanical frame most likely needs to be cleaned and lubricated. The tack strips that hold the material on to the frame are certain to have deteriorated. The window weatherstrips are surely hard and cracked, and you can bet the pads that protect the inside of the top from the frame are worn beyond reuse. So you see, there is more to replacing a convertible top than just laying on new vinyl.

We came to realize this with a project we came across: an early Nova convertible, whose owner was trying to get the car in shape for the winter. Having sat for a decade or two, this freshly painted, but non-restoredstreetmachine, was just hankering for a new drop-top.

Raising The Roof New Rubber
With new rubber, there is no reason why this drop-top can't be driven in the rain. These pieces were great and fit just as snug as the originals.

The first order of business was to disassemble and clean the manual top mechanism. The owner felt comfortable doing this since it was a simple matter of loosening some nuts and bolts, using some sandpaper and spray paint to make it look nice, and reassembling it back on the car-nothing that couldn't be accomplished during a couple of Saturday afternoons. With that part of the resto job complete, the attention was turned to lining up the correct materials. This was a step made easier by the experts at Year One Incorporated and our Nova guru, Joe Grom of Chevy II Only.

When the boxes arrived, they were packed with everything necessary (pre-cut, heavy-duty vinyl top with a new clear plastic backlight, tack strips, hold-down cables, etc.). The only thing missing to commence with giving this old car a brand-new appeal was a talented upholsterer and his air-actuated staple gun. For the all-important skill of putting the top on we turned to a trusted friend, Wanda Wells, at Wanda's Upholstery in San Bernardino, California, to perform the meticulous task.

Raising The Roof Old Rubber

Wanda, who's been stitching up custom interiors and convertible tops in street rods, race cars, and hot cruisers for more than 35 years, was more than happy to cut, stretch, glue, and staple the Nova's white top into place for our cameras. And when it was done, six hours later (the labor book calls for the job taking roughly 10 hours), what we had was one cool-looking rag-top. Hey, now that we've witnessed it being installed on this soon-to-be street cruiser, maybe we can tackle the job ourselves when it comes time to put a new top on our own Rusty Ragtop resto project. And maybe you can rise to the occasion and do your our own drop-top replacement, too.

  • Raising The Roof Tack Strip
    Included in the kit from Year One is a roll of tack strip material. This is an important part to replace, since it's where the vinyl top material is stapled to. Here our resident interior expert Wanda Wells fits a new piece into the bow of the frame.

  • Raising The Roof Oem Paint
    Another important tool when it comes to restoring the top mechanism is a can of semi-gloss black paint. Since the frame is visible from the interior, it won't hurt to make it look as clean as possible. Companies like OEM Paints offer colors to match the factory original, too.

  • Raising The Roof Fresh Start
    The rear tack strip had enough staples embedded into it for a couple of top redos. Taking them out so we had a fresh start was a chore, but a necessary one.

Since the top's frame is extremely flexible, it's important to take measurements so that the material goes on uniformly. Here, prior to installing the pads that run along each side of the frame, the distance is determined between the rear-most support arch and the sheetmetal ledge below where the rear window resides. This is important since you don't want it to be in the way of the window and you do want it to provide support for the material above the window.

    Once the correct measurements are made, the vinyl material that surrounds the foam padding is laid out from front to back. It is attached via staples and screws to each supporting crossbow that spans from side to side.

  • Raising The Roof Foam Positioning
    Next, the foam is meticulously positioned before being wrapped in the vinyl and stapled closed. Part of the purpose of the "pads" is to protect the inside of the top from the metal mechanism and to keep it from flapping in the wind.

    The next step is to install the rear window part of the top. Here the well liner is stretched out from its folded position and stapled to a tack strip that is screwed into the inside sheetmetal. The top material beneath the rear window also attaches here.

    Stretching the plastic and vinyl backlight is easier when there is a couple of other hands available. Note the flood lamp. A little heat to "soften" the material didn't hurt, either.

    Once in place and all wrinkles removed, Wanda used his trusty air stapler to fasten the backlight to the tack strip. Here's one of those parts where experience is the best tool.

    With the backlight in place the next step was to drape the top over the frame and position it correctly over the front and sides. For this task four hands are certainly better than two.

  • Raising The Roof Tack Trips
    Here's a look at the tack trips before the well liner and top material are attached. Large self-tapping screws are used to secure the strips to the inner mounting sheetmetal. But care must be taken to use the correct length fasteners. If too long a screw is used it is possible to push out the side of the external quarter panel.

With the rear section of the top secured in place, the next step is to attach these special braided wire straps along the inside edge of each side of the top. Their purpose is to keep the top material tight over the edge of each side of the frame. When the top is up and in place, the straps are pulled tight and serve to keep the sides snugly over the frame. A string is used to pull the wire strap through the sewn opening along each side of the top material.

    The next step is to stretch the front edge over the bow, mark it and trim to length, remembering to leave enough material to be stapled to the tack strip under the bow. Again, two people make this part of the install easier.

    Under the bow is the new tack strip where the material is stapled. With the top lined up to the aforementioned chalk mark, and the frame in a relaxed position, the top is glued and stapled down. Then Wanda used a razor to trim the excess material. A piece of weatherstripping will be glued here after the rolled edge is installed. Note the molded end of the side weatherstripping. This is screwed into the frame and will connect to the front seal.

    At the front end is a spring with a loop that is also screwed to the frame. This allows the strap to "stretch" while the top is lowered onto its latches. The strap is installed prior to the frame being fully extended. When installed correctly, you'll feel the strap stretching as the top is lowered onto the latches.

    The sides of the top fit under the rear side window weatherstripping, which have small studs that protrude through the channel in the frame. Once again, Wanda uses an industrial contact adhesive on both the frame and the underside of the material.

    When the adhesive is ready, the top is stretched over the side edge of the framerail and forced into the weatherstrip channel before the rubber weatherstrips are installed. At this point, the top is tight on both sides and at the front bow.

    The bead makes a nice leading edge for where the top rests above the window frame.
Raising The Roof Rub Strip

To finish off the top install, a thin rub strip is attached on the outside across the rear-most bow. This specifically made piece is designed to be stapled into the bow's tack strip and then folded over to form an edge to seal the top to the bow and prevent it from tearing away at the staples when lowered and while driving. To accurately center the strip, Wanda measured each side.

Then it is folded over. A metal wire strip under the vinyl allows the strip to maintain its shape after being folded in place.

Raising The Roof Install Complete

Finishing off the rub strip are stainless steel ends. They simply screw into the tack strip and offer a nice aesthetic touch, while also serving to keep the ends from separating apart.







Raising The Roof Stainless Steel Ends

After six hours of meticulous installation, this little drop-top was reloaded onto the H&H trailer looks. We think you'll agree that it looks like a million bucks. The next step for this Nova's owner is to install a complementary white interior, which we might add, was also sewn up at Wanda's Upholstery.
