1970 a/c ?
 

i have a 1970 c20 that im workin on, i pulled the a/c unit that was mounted under the dash because it had no compressor and a few other pieces. was this aftermarket, dealership add-on, or factory? would it be worth saving, it looks a little rough from use, and how does this affect getting parts for my truck(a/c, no a/c cab) thanks for any help identifying, here are some pics for yall.

Looks like it was dealer installed, or aftermarket. It is not factory GM. It has no bearing on the parts you need for the factory unit. If you had a factory set-up, it would be worth it to fix it up, but if you are starting from scratch, I would go with classic auto air, or vintage air for a system, because factory stuff is expensive and you have to collect it piece by piece unless you find someone else selling a complete set up

They bring a few bucks at swap meets & probably internet sales. You can get the factory underhood parts from a salvage & some fittings & hose & make it work very reasonably.
