Hey all! As the title says i plan on attempting to re install heat in my 91 z28 and i need some help. The car started its life off as a 305 tpi which was then later swapped out for a carbed 383, however when the previous owner did that he also yanked out the heat/ac and all the wiring to it. Im not gonna be putting ac back into it and im aware i will need the controls, a inner heater box, the blower motor box and a wiring harness however im in desperate need of some help on which parts are interchangeable with eachother such as the heater controls and inner box, which wiring harness and just where everything is gonna plug into or connect. Thanks in advance and any help is greatly appreciated!
