the floor pan and be repaired quite easily, i believe you can buy pre cut material to replace, as for the frame itself im not sure....ive had 2 mustangs both foxbodies and i was always having problems with the floors, they would rust and the welds would break so the seats would lean to one side. then i got smart and bought frame connectors. lol

Anything can be fixed, you just have to have some skills of your own or find a chassis shop that can fabricate metal. Many shops just don't want to do that, so they say it's irrepairable. Yes it can, it just takes some work they don't want to do. If you get the run around, go elsewhere because they just don't want to do some actual work.

The floor pans are easily replaced.

Hey eagle i know you know what your talking about, so im gonna ask a few questions, how much does it take to get your chassis fixed, and the place where the floor meets like the pillar that goes up and forms the area with the windshield, whats that called?

Can you give me an estimate parts, labor just your best guess

Thanks alot

The pic im trying to describe is the last one (second row)

...yeah the floorpans will be easy to cut out and spot weld in new ones. The rocker panel shouldn't be to hard, but you'll have to get creative. First, grind all the rust away and use a body hammer to tap out all the weak spots. Once you've done that you will know how much metal you're going to need to cover the hole. Take the body hammer and create a dent around where the rust is. large enough to fit the replacement peice of metal in and weld it into place. Then once the peice is in and the dent is lower than the normal rocker surface fill the dent with plastic. Sand smooth, prime, and paint. Or you can just cut out the entire rocker and put a fresh one in, but that would be a REAL PAIN!!

Well it will be harder to replace the entire rocker because there are a lot more welds to cut out and it requires a little more know how. You have to be really careful when cutting the spot welds so you don't cut all the way through the second layer. There is a special bit for drilling out the welds. You want to coat it in oil or you will burn it up quick. Another tool that would make this job easier would be a pnuematic air chisel so you can seperate the old part from the car once the welds are cut. I'm not sure if you can buy a replacement rocker assembly or not. But from the looks of the damages it might be the best route for you. Oh and on a lighter note, I like how you painted the rust chrome to make it look like healthy metal again. HA! I'm sure you were just trying to prevent further rust.... Rubberized undercoating is the best thing to use for that when you get your rust removed.

Yeah its temporary to hold the rust down for a little while i get a plan. https://www.certifiedfordparts.com/f...ang-parts.html
These guys offer the rocker panel and all oem parts. Which do you think i need inner or outer rocker panel, (or unfortunately both)

Thanks

That's a nice site for hard to find replacement parts. Also I have had luck just going to the junk yard and cutting the pieces out that I needed. Check 50resto.com they have replacement parts as well might be cheaper, thats were I got my floor pans and a few other body parts.
