Knee Knocker A/C

I installed Vintage Air in my 66 GT. See A/C in a 1966 Dart GT with 360 for pictures including the under dash view and parts numbers. I have not had any issues with leg clearance on the passenger side. There is also a '3 vent' version they have in the Builders Series that is even thinner. The unit I had provides A/C and heat (like I need it in Florida :) ). Hope this helps.
