My 70 coupe had air con originally, but now pretty much all that's left of it are the console controls. I was toying with the idea of connecting the dash vents (the ducts are missing) to where the vents are in the kick panels in a non air con car. Would this work? There are no holes in the inner guards at present but I cant see too many issues in putting in a couple. The air could be controlled by the dash vents, would I need inline fans as well? Resurrecting the air con would be way outside my budget from what I've seen of the parts pricing.
