'67-'72 Truck & Van interchangability

[Chevyboy1962]

Hi Guys,
My Bro-in-law & Sis had me tow there parts van(1970 C30) home for them today up in the hills. Talk about a scary ride on some narrow roads, and some with drop offs loaded down.

After taking a good look over the van there is a some parts right off the bat I know is a direct bolt into a truck. They plan on using the 350 & turbo hydramatic trans (P-N-R-D1-D2), powerglide?? and install it into my Sis's '68 swb fleetside that has no engine, trans or radiator.

What other interior parts, under hood parts, electrical could they use?
I get first crack at everything else on the van(minus radiator, engine, trans, or driveline). I'm going to snag the auto steering column, which has hazards built in, electrical harness, and pretty much everything else in the dash. Also the guage cluster resembles the '48-'53 chevy truck guages, but with the same font as found on the '67-'72 trucks. What about window regulators, inner door panels, door latches, etc?

Thursday i'm going back up there to help tear it apart, the van will be gone about a week later(home association), and sent to be recycled. I'm going to snag what I can that's good off of it for payment for towing it for them using my '77 suburban.
TIA,
David
