Update on the 36 Phaeton:
Have found and photographed two others,and decided that mine had a few issues.
It appears that the car had been wrecked at some point, and the frame must have been bent. The front cross-member was replaced with one that did not quite fit. The frame rails had patch plates welded on all four sides near the front body mounts, the running boards looked homemade, and the front fenders had been very poorly repaired.
Today I purchased an excellent parts car, that will solve all of the above, plus many others I am not reporting. Get a factory radio, heater and clock to boot.
