Cut the firewall out with the A/C car and transfer it to your 72.

Theres also classic auto air with a custom fit setup for your 72 that uses the stock non A/C controls, with a minor mod.

I don’t wanna yank out the engine to do this tho but I’ll take a look at what I need to do. I would go with the classic auto air but it’s a bit pricey, I’d rather do an underdash kit for about half the price but will see!
