Hi, I’m working with a 1981 C10 no AC. I need a replacement non AC box both in the engine compartment AND under the dash Because I found the mice had made a home in the heater box, both under the hood and under the dash. And they made a mess of EVERYTHING, the doors /flappers are very rusty and won’t move from the heat control, so I removed the box In the engine compartment. Everything is a mess I’m afraid no amount of cleaning will get rid of the smell. So I just want to replace both. Any ideas on where I can find replacements?
Thanks
