Hi & welcome.

I don't know that I can answer your question here, but based on my own experience maybe I can give a couple of pointers.

I bought a project, 64 body on a 61 chassis. All parts in boxes in the back.

Learned the hard way that there is a big difference between the 60-62 and later chassis. Sadly parts availability for the early, torsion bar chassis is limited. The big difference is that the frame rails are wider apart on the earlier frame.

On my rig a prior owner grabbed a bunch of parts off a later truck chassis including the entire front suspension with coils & five lug disc brakes. Also rear axles, etc. This was a good set up and easy to modify.

Hope that all helps as I learned the hard way!
