Classic auto air install:will 72 duster heater controls fit 73 dash ????????

OK, If late model basic non a/c uses 3 cables and no vacuum, and those cables attach and operate the same directions, maybe the earlier controller will work. Like I said, I aint dealt with all of them.
Good luck to all

I think I might give them a call so we can know what exactly we need to modify. I am not in a spot to buy this yet, but it would be nice to know and document.
