Good info on this thread. I just talked with Gary at Vintage Air. Very helpful and knows his stuff. My truck had factory air, but it was not working. Blower was weak and noisey. The controls were stiff. My original plan was to fix the stock system. After reading this thread, I think the Vintage Air system makes more sense.

The entire climate control system will be new and modern. I suspect I would spend almost the same money to get the stock system working and keep it working as the old parts I thought were good failed. And I would have the frustration of needing to repair something that I thought was done. I want to avoid work in the interior once it is buttoned up for as long as possible.

By the way, he said fitting it with a serpentine pully was no problem. I am going to be fitting a mid-nineties serp system from a 4.3L blazer on mine.
