Yard find donor question

[tmills213]

Ladies n Gents,

Went to a new salvage yard today and noticed a few potential gems. I think some of the trucks I found would make some good donor trucks but in not sure what all I could get off them. I know the front disk suspension may bolt in to my 64 c20 my which would be nice. Anything else you guys know may work?? i beleive the van is a 91ish, the brown is a late 70s, and the burb early 80s?????? I didnt have much time since my ride was in a hurry.
