Vintage Air's smallest heater/evaporater unit (mini-something) sells here for under $400, and fits under my dash.

FYI - My wife's only requirement for this project was A/C...how could I say no?

Anyway, for my build, I had to design my own compressor bracket. My total out-of-pocket for air-conditioning was under $1000...including polished compressor.
