Thank you, and I would guess 63-64 would be a little easier swap, eh?
Thank you again, now I can add one more item on "the things to do list"

Torsion or no torsion that would be the question.
Let me start by saying I haven't done my swap yet.
I have a 61 C30 panel truck.
I bought a 67 C20 drum brake crossmember assembly.
(actually I have the entire front half of a C20 pickup frame so I know where the steering box and idler arm go.)
The torsion bars go away if you swap in a more modern front suspension and then the torsion bar crossmember can go too.
The 3/4 and 1 tons have a more normal looking ladder frame, no X member. Makes it simpler to work on I think.
