A/C- non A/C conversion??

I am converting mine right now, I welded up all the holes then took the non ac box apart. I used just the half of the box that is against the firewall to make the holes i needed to drill. Drilled everything out, once completed you wont ever know my car had ac.

The box I am using is an earlier style but that is only because I like the style that has the trim ring better then the later style that just has studs sticking out
