I am still gathering bits and pieces for my 1956's A/C and recently got a second plenum assembly as the one I had was fairly rough and a while back got another pair of the rubber/foam outlet tubes. I also just got the blower fan as I had only the housing before. Oddly, my car already has the extra pulley even though it's the original VIN-matching engine. I've owned this Clipper Custom for many decades and am only just now starting to work on it.
Of course, interested in factory A/C for my 1954 Patrician. I have the blueprint which shows the entire assembly (the paper is about 8' long with all the exploded views!) but would like an actual trunk unit as a sample because the blueprint, possibly being a copy of a copy, is almost impossible to read. Anyone have one to sell or loan, even if it's a junker? I also had the rear fender scoops and dash control castings made into 3D models so those can be reproduced fairly easily.
