Hello - i am close to buying a 56 DeSoto but the heater is non functional, and the temp gauge does not work. Does that indicate cooling system problems? Assuming I buy the car and want to rebuild the heater, what is involved, in complexity and cost? I am an amateur and would probably have to send this out to be professionally rebuilt. Any ideas on cost? Any recommendations? I live in NJ.
Thanks for any help you can give.

The OE PN is (I think) 1605 274. Shows up in Section 1-48-88 of the 55-58 Mopar Parts Catalog that is referenced from Item 37 in the diagram below. Shouldn't be too tough to have one made.
