Budget underhood AC retrofit.

I can't help you doing this any better for your application. For me, I am adding AC to my slant 65 Dart wagon and am using all the factory under dash components, factory condenser, and factory horizontal drier rebuilt by Classic Air. I will be using a Sanden compressor mounted to 79 Aspen/Volare AC brackets. I will be sending the hoses to Classic Air so they can be replaced with 134-compatible hoses. The hose fittings going to the connections on the firewall and condenser will remain the same. I will have them to not install any fittings to the compressor side of the hoses plus leave them a little longer than original so new fittings suitable for the Sanden can be used and the hoses fitted to a suitable length. Electrically it will be as per original 65.
