1963

[1963chev]

I am a first time poster. Just getting started restoring a 1963 fleetside shortbox. Bought a completely rusted out 1972 longbox that runs good and the idea is to get the front end, rear end, V8, 350 turbo, power brakes and power steering out of the 72. Just got the frame of the 63 stripped down to find that the last crossmember at the rear of the frame is not "square." It is riveted in like it is stock, but there is about an inch difference. This is back where the sway control arm mounts to the frame from the rear end. Can anyone tell me if this is normal?

Also, since the frame seems to have a bit of other trash welded onto it and a few extra holes, I have been thinking of using the 72 frame. It looks like I would just have to cut the cab mounts off the 63 frame and put them on the 72. Is this right?

Then it looks like I would have to cut the 72 frame behind the cab as well as at the rear to make the longbed into a shortbed. Is this more trouble than sticking with the 63 frame? I am also going to need the trans mount off the 72. The 63 has coils in the rear and the 72 has leafs. Is one better than the other?

Lots of questions but could use some advice before I go too far. Thanks.
