Roy Rodgers you got it. Those heat exchanger are used mostly on trucks with front mount pumps. That is the first one I have seen on a midmount.
The truck came from some where on the east coast probley colded than here.
As far as the earlier instrument panel I don't know that is something you guys piked up that I know nothing about. Somebody school me on Art Deco trucks please. I would like to do a good write up for these guys. Ask as many questions as you can think of and I will make sure it gets in there.
