89 Chevy parts on my 64?

[64Magoo]

I have a nice '89 K2500 that has a blown head gasket or a cracked head I'm not sure. The PO drove the truck with no fan/fan clutch, or radiator and overheated the heck out of it. The interior is perfect so I could use the seats if I wanted to. I was wondering if any of the power steering, a/c etc. would be usable. Since it is a 4x4 I don't think any of the suspension would swap. I am planning on using the 16inch steelies off of it however.
