how hard would this be?
 

I have a 1985 suburban parts truck and a 1977 scottsdale, the 77 has no factory air, I want to swap the dash and the whole factory air system from the 85 into the 77. Is it a pretty direct swap over or are there a million little things standing in the way? Thanks

The firewall is different. I cut out the A/C firewall from my donor, then cut out my non A/C firewall and welded in the A/C piece. You will need all the vacuum lines, A/C controls, and the electrical plugs. You will either need to wire the correct plugs into your current harness or swap the entire harness for the newer one.

you might be able to cut the non A/C firewall to accept the A/C stuff...
