Floor Pans

All AMCs are unit body construction, which means the tub is the frame. Replacing rotten floors with fibreglass weakens the the structure. You need to replace the floors with steel of equal rigidity to maintain the integrity.

Hey there bud, I'm currently further down the timeline but same project as you with repairing a rusty floor, I had a lot of help from the guys here on the forum, I'm still working away at it and will post a pic soon of a completed driver's side floor section, but there's still the other four floor areas to repair, it's going to be a big job. Anyways, here's some tips for you, don't let me tell you what to do, but I'll give you some advice on how to not waste about four weeks of time... Buy a MIG welder, sort out the power supply issue, you'll need access to about 20 amps to power a good welding machine, something that requires about 15amps is not desirable, but it's still a welding machine btw... Just not as good of a performer as a 20 amp power requirement welder, get some gas, MIG gas is I think 75%argon and 25%Co2, a 55cubic foot tank which is about three feet or so tall and weighs about 45lbs will be a good start, don't bother starting with flux core, if you do, like I did, you'll probably end up eventually getting the gas because flux core is a little tougher to weld with and it's super messy, lots of Time will be spent cleaning off the slaag before you weld the same area again, MIG welding process doesn't require that step. Now for the new metal part of your work: get some hard paper board, not cardboard, it will not cut very precise shapes, but use a thicker paper from a art store, find out where the rusty floor areas are, you can smack the floor with a screw driver and see where it stops punching through the rust, once you find you perimeter of rust, cut out the same shape with the paper to make templates, or shapes, after you have your shape cut out of the paper trace that same shape out on to your new metal and cut it, then weld that into the rest of the not rusted out floor, which patches the hole, clean up the metal first so the weld will be a successful weld and will weld easy, after that, use rubbing alcohol or some degreaser to clean the areas and prime it and paint it. Welding isn't easy, but as the pieces get welded in and you can see progress, it feels good. Good luck!
