'77 Van pieces interchange with '72 GMC

you could sell the tranny for 150 or so
The seats may be of value to you
if it has a tilt, it's the one that works
if it doesn't have a tilt, the fiber optic cable for the perndl (P RND21) indicator will work on your truck, or mose stuff to sell.
Heard of ppl using the rad
heard of ppl using the shroud
no idea on motor mount stands
engine is a no brainer.
Manifolds may or may not be useable in the truck frame
I don't think you'll be able to use anything in the front suspention


if you use the 3 speed, it would be easiest to place the 350 in the inline 6 location...you can use the stands that are there already (assuming 250 and not 292)
