There is a guy here who goes by the handle "Jusride" who has a number of pulleys, and he's a great guy to deal with. However, there are a lot of different pulleys out there, and you need to make sure you're looking at the right one. You need to know the number of grooves you need (1 or 2) and the depth. (There's deep and shallow.) If you have one of each side-by-side, this makes perfect sense. Talk to him and he'll be able to work your problem out with you. He's right where you are in the pulley hunt.
