    My kit was different from that one, and I had to order a smaller belt.

      I bought those udp over the summer and put them on. Yeah you'll need a smaller belt. I can't remember which belt number though. Do a search someone on here told me the part number for the belt and it fit perfect. I wouldn't use the alternator pulley they give you though. In the rain and at night when I'd have my wipers and lights on the battery would fall drastically when I was stopped so I just put the old alt pulley back on.

            I also used a 60760 with my ASP pulley set.

            Walk into any auto parts store and tell them that's what you need, they will have it. The numbers indicate that it's a 6 rib belt that is 76" in length.

            With both pullies installed voltage output at idle will drop to 12 or lower. If your car sits at idle a lot you might want to leave your stock alternator pulley on, in which case you may need a 60755 or even a 750 belt.

              When I put back on the stock alt pulley I just used the 760 belt but it was a stretch. I'd just get the 60755 belt and leave the stock alt pulley on. It was a noticable gain for the money. It didn't kick you back in your seat but you could do burnouts longer.
