Well, like Sweater said, i do have(had) a York installed for about 3 years in my truck. I removed it before I started all my SAS work, to rebuild the compressor,however, and have not reinstalled it yet. I do not have any pictures of the install

I dont recommend or endorse doing it thisway, but it works really well haha.

Remove factory air injection pump, Cut two brackets out of 1.5 inch 90* angle iron, that will fit in front of and behind the factory bracket that is in there. Bolt them to the bottom of the compressor. Then there is a piece of quarter inch strap that is bolted to the side holes on teh compressor and attached to the small stud that is close to the block on the Original air injection pump bracket..

and so on... haha im sure that makes no sense.. It only took me about an hour to make the brackets and get the belts all lined up.. It works really well, with the 2.5 gallon VIAR tank under the bed. I will get some pictures tomorrow of Tuesday for you to look at of the brackets and stuff.
Peace
