syndr0me, regarding the spool... you really only need the pads. you can remove the diff balls from your current pulley and add the spool pads. it looks like they are only sold with the pulleys though. if you go that route, vs. drilling out the center of an old pulley, be careful as they are made of a thin and brittle material. even if they crack though it's fine, they can still be used just fine.
