I, for one, run for the hills when some nut job with a wrench in his hands suggests tackling the floorpans in his classic hot rod. Why, you ask? Put simply, on this job, there is not one single nut to turn in the entire process. Body fabricators use words such as bend, Bondo, cut, weld, etc. It's a language that very few of us speak, and when we try, we end up looking like that tourist failing to fit in with the locals.
Up here in the Northeast (and the Midwest, Northwest, New England, ...), you are almost guaranteed to find rusted floors with a few holes in them. Just about any car that sees the road salt, dirt, and grime meets this fate. So let's say you do decide you have the right stuff to tackle such a job. The seats come out first, followed by the trim that probably says "Body By Fisher." Then you start peeling up rug and find some nasty mess of sound deadening material and accrued ooze that may or may not be glowing. Now what?
As our Camaro was already...
As our Camaro was already gutted, we saved ourselves a lot of time. If tackling this job at home, make sure to rip out everything that you intend on keeping in the car. Welding sparks can damage door panels, electrical systems, steering wheels, carpets, etc. We will be replacing the steering and electrical systems, but still took extra care not to damage these in the process.
Luckily, Bob Gonier over at the Mercer County [New Jersey] Technical School knows exactly what to do and is teaching the future of the hobby the tricks of the trade when faced with ill-tempered floors. He was more than happy to get to cutting on our Camaro. In reality, we didn't have much choice. The Back To The Street '71 Camaro is going to be full of goodies, including a FatMan Fabrication front and rear suspension, GM Performance Parts ZZ454 crate engine, Level 10 Transmissions 4L60E, and much more. We weren't about to start cutting corners now ... metaphorically that is.
We called Ground Up Restoration in Meriden, Connecticut, and placed an order for both a driver- and passenger-side floorpan for the second generation Camaro. The good news is these are relatively cheap in the world of sheetmetal. As with most fabrication, the work here is extremely labor intensive and Bob ended up with several hours in the pans making sure the job was done right. "I spent a good amount of time with my students showing them the proper techniques. If I, or any other fabricator was going to tackle this job, its going to take the better part of a full week to complete," said Bob.
The fabrication went smoother than expected and we banged out these floorpans on and off in approximately two weeks. After some TLC, and a coat of primer, our floorpans looked better than when they came out of the factory. Follow along as we get to cuttin'.

 As you can see, we absolutely...  As you can see, we absolutely needed to put floorpans, especially on the passenger side. These large rust sections were breaking apart if someone looked at them the wrong way. The last thing we need is an extremity falling through the floor at 120 mph. |  First and foremost, we had...  First and foremost, we had to drill out the spot welds holding the under-braces to the original floors. We did this from the bottom, which actually made life much easier as the body was already on a rotisserie. |  Probably the most tedious...  Probably the most tedious part of the entire job was separating floor from bracing. Motivation was in the form of some screwdrivers, hammers, air chisel, and a whole lot of manual labor, but at the end of the day, the entire existing floor was scrapmetal. Mercer Votech 1, Camaro 0. |
