I purchased a set of brass bushings to replace the worn rubber ones that normally adorn the transmission-end of my shifter cables, and got them installed in about 15 minutes; it would have gone quicker, but I had to remove the intake pipe to get at them. End result: slightly more notchy feel to shifting, and combined with the B&M short shifter and Symborski shifter-plate bushings, the shifter throw is probably about as precise as it can be. Purchased from Don Greenwood (dgreen on DSMtuners).
