84 3/4 truck parts that are usable for a 66?

[CSoliz]

My buddy has a 3/4 ton '84 at his buddys house. He told me I can go over there and take what I need from it. Now, I want to grab the lower control arms, spindles, calipers, power steering box, ps pump, ps hoses, idler arm, and the distributor. Brake booster is all ready gone

My questions to you are:

Will my list of grabs work on our trucks?

Anything else that would be a worthwhile swap for our trucks?

The truck is a 8-lug, can I buy 6-lug rotors for them and slap them on that spindle?

Am I forgetting something?


Any help and opinions are appreciated.

Thanks.
