Ok all this talk about R-12 and 134 A is like Chevy vs Ford. Both do the job well. Both have the same things bad about them but if both systems are working right they will blow 30* air at the vents.

My 71 C 10 has had mods done by me and it blows 30* no matter what and it's been in operation for years. Yes it has the factory basic system inside the cab but the out side is all newer stuff.

I went with Classic air stuff along with late model Chevy truck stuff and the hose connections are like anything else just buy what you need. I bought Classic air kit with all the fittings, compressor, condenser and put it all together had the lines made up and it works great.

These are the old 305 TPI setup.





The 6.0 with same setup.




In my 64 SS Impala I used everything in the car when I bought it which per the owner at the time had been swapped out. I put new lines and drier in it with 134a and it blows 32* all day long. I'm running the older A-6 compressor in the car also. See how the lines are curled up. I took it all a part and had longer lines made and hid them inside the fender to clean that side up.
