After three years of freezing my butt off going from Indianapolis to the Morris pile up , i finally broke down and installed a Hadees heater in my model A. ( a antique store find some time ago) Which worked very well. When discussing this with Don Basala ( DB Sprinters Indianapolis) i mentioned the heater discussion on this board a few weeks ago. Donnie said ,i made some of those up a few years ago and didnt sell a one of them. I walked over to see his "Too Cool" heater project and was very impressed with the quality and size of the unit. He gets $139.00 for them. Thought it was a pretty good deal.
