A/C Conversion Advice
I'm torn on whether to give up on my non a/c to a/c conversion or just bite the bullet and go with an aftermarket a/c kit (VA, Old Air, etc.)
I have a non a/c cab and purchased an a/c system on craigslist from a 70 chevy. (A/C box, condenser, old compressor, actuators, most of the brackets, etc.) I started the non a/c to a/c conversion by modifying the firewall and installing the a/c box with a new evaporator. The system I bought didn't come with the poa valve, and now I'm torn on how to finish this up. Do I go with a poa eliminator setup? Accumulator and orifice tube setup? Is it worth seeing if the old A6 compressor will work? Or should I go with a newer one? Any advice/help would be greatly appreciated!

Re: A/C Conversion Advice
Thanks Andy. Which kit are you referring to? Would I need to get a different evaporator? Would I need to have hoses made?

Re: A/C Conversion Advice
If you need a rebuilt poa valve, I have them. This way you don't need to buy another evaporator. You could also get an aluminum modern version of the steel a6.

Re: A/C Conversion Advice
My aftermarket old air kit sucks. It will be coming out this winter and replaced with a original ac system

Re: A/C Conversion Advice
Thanks for the tips. I'm leaning towards finishing up the factory A/C, but not sure about which compressor and valves. A6 or sanden? POA, POA eliminator with cycling, or accumulator/orifice tube setup. It gets well over 100 degrees here in the summer.

Re: A/C Conversion Advice
If you are installing a factory system, go with an aluminum aftermarket replacement for the A/6 that fits the brackets/hoses. Use R-12 and have a system that works as it was designed and will freeze you out of the cab idling in 100 plus degree weather. No need to change anything else. The cost of R-134 here is almost the same as R-12 anymore (which can be found at swapmeets, CL, and eBay)
