I sure wouldn't swap in a newer complete frame... that pretty much doubles the required skill level of the builder.
I think I looked at a '63 truck when I was debating a new cab. (The cab was wrong anyway)

IIRC, though, the frame was flat, and didn't have the "kick" where the front cross-member bolts up. Here's a pic of my 66 GMC frame, so you can see what I mean.


The newer (1976) cross-member was all but a "bolt-in" swap, (see my journal) but the stance is just a bit wider.

I *still* don't have it on the road yet, but I'm hoping it will be fine.
