I have a '66 that had a Thrift heater in it (it has one knob with a cable attached). I just got a heater out of a truck my neighbor was scrapping, I think it was a '62 or '63, and it had the Deluxe heater in it (4 control knobs and cables). The heater that was in my truck is really in bad shape...Almost nothing but the cases are salvageable. The one I just got looks to be in decent condition. My question is, can I mount it up and put the controls into the dash of my '66, or is there any problem that you can see with that? I think it can be done. although I may have to use a '64 and on control unit (the control unit in the '63 was trashed, and I didn't see a good source for the 4 lever unit, just the later 3 lever). That would be easily overcome by just leaving the floor/defrost lever to be manually operated, I think....Any thoughts?
