Anybody installed an A/C system in a '55/'56 Merc? After sweating it out all summer I gotta do something; the old 4/70 A/C just won't cut it. So my question is, what kit did you use and how did it go? Anybody with a Ford from the same years please chime in; the cars are very similar under the hood and dash. My car had factory air; the old Novi Air system with the evaporator under the package tray and the 2 clear ducts in the rear window. The owner previous to the guy I bought the car from took it out and chunked it. The only thing left of it is the crank pulley. I'm looking to install one of the A/C-heat-defrost systems under the dash. Opinions on brands welcomed.
