so I finally got the car on ramps (anyone with a non textured floor knows my pain) and just got a chance to look at the alternator... Heres what the back of it looks like.

I'm thinking its the bottom right one in the first pic, but I really dont know, and my manuals dont say anything

Is it the right part, because it looks totally different then anything on the alt, and has different numbers on the back (but same company)

Thanks alot
