I just bought an ebay short shifter, it came with the shift lever attached to that bracket with the pointy end and the bushing that goes into the other end of the bracket. My shifter is really sloppy so I'm going to replace bushings while I'm in there, so which ones should I replace? And what kind of bushings should I get? Do polyurethane bushings make a big difference? Are there any local or Canadian stores that sell these things for a good price?
