Used OEM 105 amp alternator off of a 2005 LLY. GM part number 88877296 / ACDelco part number 335-1086. Good working condition, only removed so I could upgrade to a higher output alternator with my e-fan installation. Fits many different models and years of GM vehicles. O'reilly Auto has a good compatibility chart if you search part number 335-1086 on their web site.

$40 shipped OBO to the lower 48.
