Re: how hard is it to switch cabs?
The GMC dashes '60-'66 are the same, with 1 hump, just the guage clusters were different.  Chevy guage cluster will not work in a GMC dash. Any '63-'66 truck cabs are interchangable (1/2 ton) the 3/4 ton rear cab mounts use a different rubber mount.
The '63-'66 GMC frames have leaf spring rear end setups, and chevy's had trailing arms '60-'66. The good thing about having the leaf spring setup in the rear on the GMC's, you can mount just about any rearend right up, and be done.
