Current offerings for the shift linkage bushings is for the following:
04 STi
05 STi
06 STi
05 LGT
06 5MT - all models
We are working on a retrofit kit for pre-06 5MT's.
The problem with the pre-06 linkages is that there is a rivet holding the tranny side clevis to the linkage trunnion. We don't think it's a good idea to ask people to grind off that rivet as not everyone has a grinder sitting around, and the potential to screw it up is high. Instead the new kit will have a new tranny side clevis, a new linkage trunnion, the set of 4 bushings, two new spacer sleeves, and two new bolts (one will have to be a custom step screw so you can continue to use your stock control rod).
