is there any a/c unit smaller then the vintage air mini? its about 2 inches to big it hits the dash when i put the mock up in? Or is there any other units i can use?

 

I used the Vintage Air Gen II Compac and had plenty of room. I don't think it's smaller, but the dimensions might allow for a better fit.

 

i did change the firewall to a smooth one. It was one from direct sheet metal out of southern california. i was seeing if vintage air had any smaller ones then the mini ? or if anyone used something else that would work?
