Update to the update. I now have in dash vintage air. Its the compac II system. The previous underdash set up blows it out of the water!!! The vintage air just doesnt have the volume of air. It still cools but needs to be one high. At least I have heat. But.... the vintage air controls are bad and I need to send it back. Not to happy with vintage air.
Update on the A/C. It works!! Blows Ice cold. I used the factory 5.3 a/c compressor hooked to a cheap underdash a/c unit. The unit pushes a lot of air and cools the cab very quickly. I got my a/c working in a non a/c truck for about 480$ I did have to remove my heater so thats a negative but later on when I can afford a indash unit I will install that. Happy driving with the windows up in high 90's heat.
