Help trying to figure out my A/C compressor type

[TAZ DEVIL]

Hey guys, I'm trying to cut costs on a A/C repair on my truck by with having some pre bought parts before I take it to the shop.

 I'd like to have a compressor and dryer on hand if needed.

 I just don't know what model compressor is currently on it.

 It's OEM. Truck is 2002 2500HD 4X4 crew/short. 6L, LS

 Any info would help.

Thanks anyways. I went to dootalk and got info. 

 Funny how a snowmobile website will help a guy out.
