Sorry, but the orientation oof thef heater in the pictures isn't clear to me. More pictures would be helpful, also commentary about just where the heater is installed. The above picture with what appears to be a garage door on the far right, is the car on a rotisserie?

Yes, car is in a roll over frame and is sitting with the passenger side down. Was a lot easier to do the cutting and welding needed for the installation this way. Heater for the A and B T5 cars was secured to the rear engine compartment wall with large hose clamp type straps through brackets on the rear wall. Bill Sargent
