Greatings - I'm investigating installing AC in my 72 C10 307 with a non-air cab. I've found Vintage Air (Gen II and IV), Old Air, Nostalgic, Classic Auto, and LMC on line. Hoping some of you can provide some feedback of pros/cons and if I missed any manufactures. I'm curious about Classic Auto and LMC... are their kits made by one of the other's on my list? Most of the usual vendors carry AC kits and list the provider with Vintage Air being the most popular.
Some things I'm looking for are "in dash" vents, cost, and reliability. This will be a big investment for me and want the most bang for the buck.

Thanks, Eric

Hmm... 50 people have read this post and no responses... none of you have installed an AC kit into your vintage pickup? How about any car / truck?

Another thought has been the idea of transplanting a factory AC from a donor 67 - 72 truck. Has anyone done this?

I'll provide input on my solution:
- Factory parts for vents, controls, vacuum valves
- Replaced old, unreliable A6 compressor with a Sanden compressor and brackets from Vintage Air
- Swapped to a parallel flow condenser (maybe not really necessary because the original condenser is large)
- Used Ford blue orifice instead of GM white
- charge to R134a and PAG oil at about 75% of original R12 charge. Using standard refrigerant products makes it easy to find places to recharge and work on it.
- New filter/drier and O-rings
- Had custom barrier hoses made. This might not be needed if you get the right adapter for the Sanden to adapt compressor to OEM hoses, and if you use an OEM condenser. I know there are places that sell the adapter for the Sanden (Old Air Products, I think).
- OEM steel fan and HD fan clutch

I'm also using a Champion 3 row radiator from Jegs, Stewart Stage One iron water pump, and high flow Stewart 195 degree thermostat. Temps are stable at 195-200 degress while idling with the A/C on in 90+ degree weather.

Thankyou for your input! So if I understand, you started with a factory air truck and replaced several main componets and converted to R134... correct?

Eric, I am a little confused you live in Minnesota and probably get in the summer the mid 70's, so just turn inward your wing windows and open your lower two side vents and be done with it.

Funny! Just returned from AZ (Sedona and Grand Canyon) and appreciate the desert dry heat, here in Minnesota in the summer months it's very common to have temps in the 80s and 90s, even breaking 100 sometimes and super humid! It's the humidity that kills me. Growing up here in the 50s and 60s I'm not sure how we survived with only wing vents and windows down but I do remember some mighty uncomfortable family vacations with everyone hot and crabby .
To the point, there are many days here in the summer where I would like to drive the pickup but elect to drive my daily driver with the AC. Getting soft in my old age.

I agree humidity does S U C K. Here in the lower desert (palm springs area) humidity is compounded by all the "Golf Courses" with there lakes/ponds and there heavily watered grass. Yes I do also drive my daily a/c driver but will also not use the a/c form time to time. All my/our families vacations was in a Cadillac so we were quite comfortable. Good luck with finding/getting the kind of A/c you want. Just about a year ago I rescued a 72 C10 (cab only)from the Crusher having all its factory a/c components but ended up selling it, could have probably helped you if you wanted all factory stuff.

75GMC has good info for you and you could find a 67-72 Dash to install and get your stock vents and go from there. A little bit of work but is quite doable.
