My brand new rebuilt alternator crapped out on me so i went to the yard and picked up a d15 alternator out of a 92-95 civic hatch.

Got it all in and buttoned up but the alternator belt is to dam short, seems like by a good 2 inches with the alt all the way forward

Is there a specific product number I need to pick up or should I just go buy a generic drive belt form home depot, do they last as long?

Thanks
