I have a leaky evaporator in my '85. I have all but the dash and about half the console removed the from the interior as part of carpet replacement/Dynamat install and have also been considering a VintageAir install. The company I work for is a VA dealer, so seeing what others have done here previously is of particular interest.
I'm not concerned with maintaining the original cable controls but want whatever mods I make to be reversible should the desire ever strike a future owner! My current thought is to use this VA control where the radio was located, and then a simple 2 3/8" deep double DIN stereo where the console vents were located. Vents would be re-located to a 3D printed plenum that fits where the dash speaker was located (and is a shallow storage area for collecting junk on my '85).
