Is there a way to tell which alternator I have just by looking at or or measuring the case? I'm trying to figure out if this is the 105, 130 or 140 amp but I don't remember if this is the one that came with my 5.3 or if I bought one from a LS1. There's some numbers on side of the case: 2010/12/10 1/1 0005

I was thinking its from a LS1 too. I tried google for some pics but that didnt help much. I remembered buying the alt bracket from a guy but I didnt remember if i got the alt from him too. I guess I did. Thanks fellas.
