This inquiry from a Mustang owner reflects the challenge of constructing an A/C unit with parts from a variety of sources, and of finding parts that need to work with both original and non-original components.
I’m trying to sort out the components for an add-on A/C unit in a 64 F-100. I have a few early Mustang units so that’s what I’m using inside. I will mount a Unicla UP170 compressor low on the passenger side of the engine. I need to determine the proper size condenser for this given that I’ll be using 134a instead of the original R12. I have a 27″ x 16″ opening in the core support, and a non-original crossflow radiator that doesn’t mount like the OEM 64 F-100 unit did. I’d appreciate any input.
