Vintage Air Gen 2 Compac. Pretty big to fit it, but it did indeed fit with a little persuasion of sheet metal and some rough fab/welding.
Local AC shop crimped the fittings free as long as I bought the hoses/fittings from them. Nice bulkhead fittings shown thru the firewall save a few bucks vs. the male-male ones typically used.
I cut out my factory slider stuff in the center, leaving a little material around the perimeter, cut and painted a piece of aluminum, and screwed onto that material. These electric controls from VA are super nice and have a nice glow at night when hooked into the IP lights.
AC rheostat directly carries the current for the AC clutch, actually with the binary switch in between that shuts off the compressor for excessively low or high pressure. Bypassed the PCM, only negative is that I have to manually turn on fans.
Used Billet Specialties AC hose clamps, modified with longer bolts and sleeves to act as mounting posts through the sheet metal.
