Replacing Floor Panel
I just found out that the floor in my '71 Nova project is rusted through right below the brake pedal. My basic question is where do you get a replacement piece for that? Can you use a flat piece of 20 gage or how do you reproduce those stiffener ridges in the original?

Believe me...any and all advice is welcome. This is a lot more than I have ever tried doing before. :confused:

Can you put up a picture? Maybe mock up a templete with cardboard and trace it onto some sheetmetal to be rivited or welded after cutting to size.
Rust repairs are a rewarding task...
*You can do it!!

I would use 18 ga. You can put the ridges in with a bead roller. This would keep it from "sproinging".

Buying a replacement section would probably be easier and more accurate.

Thanks for the tips. I will try to post a pic. The last owner smeared some kind of plastic sealer stuff on it, so now that's in the way, too! When I pop in the replacement sheet, is it better to lap the edges or to but-weld them? Either way I get to learn how, so I'd rather do it the best way.

Well......I still can't figure out how to insert an image...sorry. I'll try to do some homework and attach it later.

Whoa!! There it is!!

Wow...Milo! I just visited your explanations of replacing rust and doing Bondo. Best explanations I have ever seen. Thanks a lot!! :thumbup:

clean up all the rust around the hole and see just how large of an area needs to be replaced. Make a patch and bend it to fit the contour, when the fit is good lay it on top of the hole area and scribe around it. Cut the scribe line and fit the patch. When the patch fit's good tack weld in place and continue to tack around the perimeter untill it is completely welded in. Grind your welds down and clean the metal, apply epoxy top and bottom, finish off the underside with Everglass, primer and paint, paint the topside. That's the basics. Good clean metal makes for easy welding. A good fitting patch makes for easy finishing. Bob

After installing new sheet metal in my truck, I used the pick side of a body hammer and tapped a diagonal pattern in it. It doesn't gaboing at all.

You can see in the picture the dust settled in the little crease.
