Okay, so I think I'm confused. My 55 1st GMC has an empty hole in the dash where I believe the heater control was originally installed. The current hearter control is one of the aftermarket type things, located under the dash. The heater is the standard sort, though it looks like the truck once had a delux heater in it.
I have a '47 Chevy with a delux heater, and the original switch and controls. I want to update to a 12-volt motor, and put the delux heater from the '47 in my 55 1st.
Will this work?
