Similar to Valyidol's post, I didn't want to hijack his, I'm trying to fit a 96' HVAC system into my 86'. I had to hack my trans tunnel and remove my engine bay side of my 86' Crew Cab HVAC. The GMT400 system is almost all under the dash, electronically controlled, and a lot cheaper then a Vintage Air setup. With my Cummins swap I also don't have a vacuum source. I realize the lines will be custom to go between the GM condensor and the Cummins compressor and evaporator but I'm hoping I can make it work. The GM compressor looks like it might bolt to the Cummins... Maybe I can use all GM components.
I'm looking for help on how to remove the GMT400 system and if it will fit in a square body dash. I'm not apposed to cutting and modifying.
Any help/pics would be appreciated. I'll detail my progress as I get into it.
