My brother and I just bought a 70 Mach I to restore and resell. We have done at least a dozen 64-70's over the years, but it's been mostly body restoration; fenders, quarters, torque boxes, paint, interior, all no problem. But, we are venturing into the "unknown" now with these frame problems. Luckily we have good donor frame sections. We have the car stripped down (no motor/transmission or fenders) and we're just kinda lookin' for any tips from anyone who has done this.
I tried using the search function, but mostly I find new frame section replacement.
Any help would be appreciated.

Here's a couple pics of what we're dealing with.
The front and rear frames are shot. Completely rusted out.

and here's the donor frame sections, front and rear.
I'll be taking pics during the process.
Wish us luck.

The rest of the car's in surprisingly good shape. Lucky for us the rocker's are very solid. That'll make this frame swap a lot easier. We're cutting the old floors today.
This is a 351 shaker hood car

Nothin' huh?
Okay, my mistake. I must have dialed the wrong number.
Sorry

Dont hang up yet Bill,
its just that pics like that scare us to the core!, No really,
what i can offer is this. set the frame in a roitsserie or stands and get GOOD dimensions from things that are not going to change like the top corners of the windshield and a fixed spot on the firewall and same with the trunk area. Remember this is and X,Y,Z deal, you have to hit all 3 for the car not to look like is frenkenstien. I say a fixed spot because you have to go back to that spot when verifying your new parts. If you have the frame on 1' blocks when you measure for teardown make sure you are on the same blocks and stilll measure 1' when its time to verify your new spots. Take a crapload of pictures, some video and remember to tack stuff up before going to town with teh wire welder, metal pulls as it is welded/heated unevenly, dry fit everything down to the fender bolts and chrome before you weld
Good luck man, I dont have the gizzard to do that much any more. show us pics along the way
