So are we going with R-12 or R-134a?

I'm putting together a shopping list, as an update I have:
2008 6.0 LS2 Trailblazer SS engine (no AC currently) Carburated.
1976 Body, with Front AC only
Adding Rear AC Donor was an 1986 Suburban

Shopping List
1. AC O-ring kit
2. Oil for o-rings (PAG for R134?)
3. Compressor (from the Trailblazer)
4. A/C Receiver Drier / Accumulator Should come with new compressor
5. High mount bracket for compressor
6. A/C Refrigerant Hose ( for rear AC )
7. Condenser (Radiator 1986)

Going to add some kind of insulation on the roof under the headliner.
Not sure what to use yet. Might just go with cheap Aluminum bubble wrap from Home depot gluing it on with 3M spray 90 adhesive (using this for the headliner also).

I guess I need a way to connect the 1976 Controls to the new 2008 Compressor.
No idea how to do that yet.
