Even though its now in the 80s I worked on the heater,the heater I got must had the smallest motor ever made on it and I did pick up a small motor for a 39 car but it was still too long. I had to make new brackets to attach it to the housing and drill a hole so the rear bearing bulge on the motor would clear but I think its ready to assemble. Now to find the reproduction knobs I bought a few years ago.
