Floor Pan Replacement Help
I'm about to replace the floor pans in my 1981 RX-7 and was looking for some help. This is not the first floor pan replacement that I've done but I was just looking for some advice and or troubles that people ran into when replacing the pans in their 7. Any help would be appreciated. Thanks

weld in flat metal dude, that way you have nothing to worry about. then you can clean up all your wires and have no carpet and can decorate the floor with diamond plate.

Now I have a question for you. Where did you get new floorpans? Or are you replacing them with sheetmetal? Cant help with your question sorry. Never had that problem, just the usual cancer in the wheel wells.

New Car? THAT'S OUT OF THE QUESTION! What's the fun in that? Carl, i'm goin with just flat sheet metal, cold rolled 20 gauge, or perhaps galvanized, to prevent the problem from occuring again

I'd go with metal a little thicker than 20gauge. Otherwise as you drive down the road your car will make noises like a Coke can being bent back and forth. OK maybe not that bad but you get the idea. Thats why there are all those bends in the stock floor, to stiffen it up. Don't breath as you weld if you go with galvized, better yet, skip the galvinized.

Not having a flimsy rusty piece of **** is always a good time
unless you have alot of time on your hands and enjoy fixing up cars that aern't worth it.
I know a guy who has a totaled 80's Ford Probe for sale if you're interested in resurecting that piece of **** as well.
If the floor pans in your car need replacing, so does your car! 1G rx7s aernt expensive, go buy one that's worth spending some time with.
Not being an ***,

Some of you guys obviously don't enjoy doing what other enjoy. Floor pans aren't that hard to do. You may want to see if you can find someone with a bead roller to run a few beads down the panel for strength. Whatever you do, do not use galvanized. You will seriously regret that later. It will make you really sick. If you can't get it bead rolled, maybe try to reinforce it with some flatstock or small angle. Good Luck, I'm doing chemo. on my car right now also.
In some regions it's just not an option to find another Rx-7 that's rustfree whenever you get a rust hole.

Checked my wheel wells, they're suprisingly solid. the sunroof seal leaked for a long time so it had a new interior when i bought it, just the floor pans are ****. I've replaced floor pans in a lot of cars before, because I work at a restoration shop. I was just wondering if anyone had any specific problems when replacing theirs to help me know what i'm getting into. And Alex...why are you on the forum if you're just gonna be a **** about other people trying to get their cars back to their original condition?

A long time ago, I wanted to change the floor pan of my (don't laugh) Pinto.
I checked with the dealership and found that I could purchase a new floor pan for my '71 Pinto (in 82) for $600.
The price was reasonable, but I could find no shop or information as to how to undo the unit body and put in the new floor.
It seems a good idea, but I don't think it is practical to execute.

Well, I wish I new that (or how to do that) 25 years ago 
So, you are saying that once everthing was removed from inside the car, and the underside, I would just break the welds along the floor pan and slide in a new one.
That would still have been a lot of work! And considering that I did most of my work in a parking space in the middle of a city block, it couldn't have been done (by me) anyway.
Besides, putting a new floor into the Pinto would have kept me from making the leap to my first RX-7
