DavidF, looks like you'll have a great installation!

I'm adding a link to provide a few pix that might help you and to show a few fun things that I did on my installation. My attempt was to make mine look like a dealer-installed accessory if it had been available in 1957.

My evaporator is mounted under the seat because I did not want to remove the original deluxe heater or modify the dash. I couldn't mount a pseudo Cool-Pac unit (available as an option starting in 1959) under the dash because of the 4 speed and floor-mounted emergency brake on my 3/4 ton, so I went under the seat instead.

I run off one belt. I made my own brackets for the compressor and the alternator. I did mine inverse of many installations...mine has the compressor on the top and the alternator on the bottom. The one mounted on top will be easier to work on...personally, my preference was to have more elbow room to tinker with the compressor.

I tried to make my compressor look 'old school' by painting it black and adding a metal Harrison Air Conditioning tag to it. I used my metal punches to mark the metal tag 'R134A' and the installation date. It was an attempt to hide a modern compressor in plain view. I wanted it to look like a natural component of the truck.

I removed the ashtray and replaced it with an A/C control plate that I fabricated to fit into the factory opening. I wanted it to look symmetrical to the heater controls on the other side of the radio delete plate. The modified a metal Harrison Air Conditioning tag to act as a brand label for the controls that I fabricated. Once again, this was an attempt to make it look like a dealer-installed option had one been available.

I didn't have a kit because there wasn't one available to do an installation the way I wanted it done. I was able to use off-the-shelf parts for the A/C components combined with some self-fabricated ones to get the look I wanted.

Good luck,

Maybellene
