As an addendum, I also noticed that the parts book lists only a handful of models and for some 1951, 1952 and 1953 models, it shows PA422406; for some 1954 models, it shows PA444644 but I am unaware of any firewall cutout or cable differences and do not understand why only a few models are listed for each when all had the heater available. I am looking in the Accessory section and perhaps the heater was standard equipment on the others but if so I could not locate it in the appropriate section of the parts book.
