thanks, the 2 problems with restoring an a/c box is 1: the cost of replacing the heater core (way up there) and 2: the vacuum pods (don't have a source for there replacement or repair). now with that being said, i did restore a heater box with a/c for a 68 dart. i did get lucky, the customer did not want the evaporator reinstalled and all of the vacuum pods were in good condition. also on A and E bodies the heater core and evap are seperate. B bodies had to be different. i priced it out once. to do an a/c box for a B body, if the vac pods are good would end up around a grand! that is alot of money to put up front for me.
