My best "find" at a local salvage yard:
4 bolt rear end (complete)
eprom ecu (91-94)
awd transmission w/t-case (shifted perfectly)
complete head with intake manifold and throttle body
14b turbocharger
A few other misc pieces.
Grand total: $165
I think I've pulled 3 4 bolt rear ends out of salvage yards years ago. They ranged from $16-60
