Suburban A/C fix + Vintage Air?

[swissarmychainsaw]

Hey all. I have a 1976 GMC Suburban, with a 6.0 LS2 (carb'd) out of a trailblazer ss. (bought it this way).

My cab has factory (front-only) A/C and it seems that all the stock parts are there except for the compressor and lines.

How feasible is this:
Uses all the stock components for the front A/C.
Add the LS appropriate compressor/bracket.
Use Factory switches (so the temp control etc. is stock)

Somehow Tee off this and add a Vintage Air for the rear, and make that switched so you could run them independently.

I have read that some guys have done this with a mini/slimline.

Is fairly doable? I honestly know NOTHING about A/C and have been reading up on it.
It seems like a fairly straight forward project (hahaha).
