Re: AC heater box in bad shape

Hello
I bought another heater box. I compared them both and mine is the same as the AC box my truck came with. However, I believe my AC was not from the factory I believe it was dealer installed the cut hole in firewall and heater box was cut crudely. I think the dealership converted my heater box with a factory parts kit. I don’t think anyone else messed with this box besides me. I’m going to try evaopo rust and see if I can’t get the flap out of the rusty box and I
Put it in the new box.
