nice score
same swap i did on my 88 suburban

if your still able to get parts off the donor truck
grab the wiper linkage and all associated parts, you DONT need the wiper motor.
the linkage and wiper posts are different then the ones on your truck now.
the 70s linkage attaches to the newer motor, the wiper posts will only match up with one mounting hole, youll have to mark and drill a second hole.
also grab the plastic mesh/grate peice that covers that area, also different.

also if your keeping a/c your gonna have to get a little creative
the 70s trucks used a small condensor compared to the newer style
i carefully cut the rad support until the condensor fit
