Old vs New

I have a 68 that has factory air and it seems as if everything is there. The compressor is locked up so it is not working now. My question is if I fix and update what I have will an original equipment ac system cool a black on black car as well as a system like vintage air? What are your experiences...

Re: Old vs New

My '67 has factory A/C and was black on black when I bought it 30 yrs ago. It cooled just fine for many years. With the recent LT1 swap, I'm running the compressor that came with the engine with the original evaporator, a stock replacement condenser, and a POA eliminator with the original expansion valve. It cools as well as it ever did using R134 refrigerant.

Thanks for the advice. Im thinking I will go with what I have and if it doesnt work out then I can save for a new system.

Re: Old vs New

Keep your inside controls and underhood suitcase.

If you don't want to spring for a modern low HP draw compressor, just get a replacement A-6 and convert it to R-134a compatible oil. You will have to swap your existing hoses out for barrier hose in order to run R-134a, but if you still have the original hoses, it's probably past time.

I have a '67 with AC in FL and enjoying the car in summer requires good AC. I have a hybrid system using R-134a, a reconfigured POA, new parallel type condenser, new barrier hoses and the Sanden compressor. Works just fine.

You don't need the POA eliminator, just dissassemble your top hose (after safely discharging your system with a freon recovery system), look into the fat end of the POA for the small nut (5/32) and screw it out (CCW) a 1/4 turn. The POA eliminator cycles the compressor and puts extra wear on the clutch plus it costs $100.
