I want to remove the AC heater box on the firewall and replace with non ac box. Is this as easy as it sounds or do I have to change the inner box, heater core, and blower motor for the heat to function? Thanks
Firewall setup is different for A/C versus non- A/C cars. You will have to get an aftermarket cover to replace the A/C stuff. Be prepared to take out the dash...AND the engine...
Ok well, Not what I was thinking/hoping. I was thinking just swap the exterior ac box with a non ac box like this https://www.yearone.com/Product/1964-72-skylark-gs/yd64 So the bolt pattern is different and none of the interior side will work with a non ac box? Would like to keep the heat and the ac is missing too many pieces, and the headers I have a line on I believe would interfere with the current ac box.
everything is different-inside heater box, outside box, dash, controls (vac vs cable) and unless you put the astro ventilation in, its gonna be HOT on that car.
