That floor is pretty funky. Listen, first off, the rear frame rails are pulled in towards each other. In other words the distance between them is less now than before. When the crossmember gets pushed in like that it is effectively "shortened". Get a straight piece of wire a foot long and bend it in the middle, now measure the distance between the two ends, get my point?

So those rails ARE in towards the middle a little. THUS, the quarters are in as well, as mentioned in another post.

You will need to cut out that rear crossmember and replace it, both inner and outer and that may not be able to be done as an assembly. You may need to cut it out, inner and outer and weld it in, inner and then outer.

That means you may need to buy new. You could splice it, if you do this right, with a "Butt weld with backing" by putting a sleeve in the thing and welding the gap up with the weld going into that sleeve you could make it strong enough. But you really probably should buy new and replace both the inner and the outer.

The floor could be replaced in the center only. Just cut right down the middle of the flange that it sits on. Then you cut out the donor the same way, and butt weld it thru the gap to the flange under it. If you plan on doing this I can walk you thru it. That was kind of a short to the point explaination.

But after you get that floor removed you should be able to jack out the rails into shape. You need to get a good bumper reinforcement to use as a guide to be sure the rails are where they should be.

You should also get the replacement doors. You WILL need them to do this repair. After you get the frame out where the bumper reinforcment fits, then you need to get the doors on and see how they fit.
