Yes, not structurally bad, but pitted. Funny, the 76 Impala subframe I put on the car, was in worse shape than the 56 Olds frame!

Yeah, most of the hard part of the body is done. So busy I don't take pics all the time! About the frame, I originally was going to do a full frame, but there was some structural damage on the back of the frame, so I just used the front sub.
When you come down to it, body mounts are super easy, Dennis! On the Olds, I only had to take the radiator support and bumper crossmember from the 56 frame and adapt it to the Impala sub. But on the Vette/GTO project I had to make all the body mounts. I just took a piece of 2 x 3 or 2 x 4, depending on how far from the rail, the mount was, angle cut it, and drilled the hole. Here's a pic of one of the mounts from the GTO. It's low on the frame, because we channeled the car a bit to get it lower.
Leveling is time consuming, but straight forward. Level the chassis, ALL around. then suspend the body over it, exactly where it belongs, level IT out, and put your mounts in. At this point I prefer to use metal, or wood spacers, instead of the rubber mounts, as they don't compress to confuse things, and I don't burn up good bushings welding too close to them.

On the bushings do you actual rubber ones or do you use Urethane?

I have to make new ones for the Studebaker project if I ever get back to it.

In that picture I see your using a Frame Table I have yet to make my own, I have some 12 Inch I beam to make one from some day I will get around to it.

I also see that Frame rail looks Brand new, did you bend it your self? or was it purchased?

Dennis, I prefer using Polygraphite bushings, they don't squeak like regular Poly. If I can't get them, rubber will do. Those rails , for the GTO, as well as a chassis we're doing for Kenny's 54 Plymouth, we had bent at Art Morrison's. We spec'd out the bends, I believe 6 per chassis, and then put the frame together using them. No one made frames for the cars, with Vette C4 parts, so we had to make our own. And with the bends where we needed them, no one could do the bends so close to each other. So we pieced them together. Here's a shot of the GTO frame, before I added the crossmembers. It used side rails bent inwards, and a front kick-up, and the "over the rear" section, so 3 bent pieces per side.
