for the most part the A/C should be almost the same across the years... only the minor differences depending on engine and modifications done in the past. Looking at the A/C setup in my 76 truck with 350 was almost the same as my 91 burb with 454 (no rear air)...

In the past 30 years about 90% of Fords are still on the road, the other 10% made it home.

Really? My 73 Suburban A/C pump is way different than the one on the 91 engine that will be going into my Suburban. I'll have to figure out how to hook up the A/C lines from the 91 A/C pump to the 73 Suburban once I get to that point.
