I think I have pretty much decided to go newer aftermarket under the hood. the sanden compressor retrofit with new condenser, drier, lines, etc. Classic has a kit for all that stuff and sounds like the easiest way to get it going.
I think I am going to do a little work on it this weekend and see if I can get the blower working and see if all the switches and things work. That will help me in deciding on a budgetary stand point.
If all the switches and what not work then, I will look into a DMT seal kit and see about rebuilding the air box, my only real concern is the evaporator, if its corroded inside or has a leak or what not.
