my 66 still has all of its stock components and I think it might be at least semi-functional once I replace all the control cables. Currently has no charge in it which could be a nightmare in itself if the evaporator is leaking. I’m going to attempt the cables first and see where it goes from there. Before I get too far with it, would it be worth fixing from a cool/hot function standpoint or should I just bite the radish for a vintage air system to ensure I actually get cold/warm air when needed? Cost might be the same to repair old or replace with new stuff.
