1962 GMC One Ton

[69 C10 LWB]

Last week I posted about turning a C10 into a C20. While it looks like an easy project I now have a chance to rescue a 1962 GMC. The cab is in better shape and its different from everything else out there so I am hoping this leads to something cool. Before I pull the trigger Id like to confirm a few things that everyone else here probably already knows. Ive searched around and cant find many threads on converting 1 ton front suspension and engine swaps that dont also swap the old 4 spd out.

1. Will my 73 3/4 ton crossmember and suspension still bolt up to the 62 1 ton frame? I know it will require the crossmember swap because the truck has torsion bars now and I dont know condition of front suspension and may wait until its needed, but I dont want to plan a project I cant do.

2. The truck has a non running V6 which Im kind of excited about, I think the old engines are pretty cool. If the V6 has a terminal problem can I use the same trans with the small block I already have? I know I will need a bellhousing but did GMC use a different input shaft on the SM420 with the 305 V6?
