of what you have and what bush you're not sure about.
If its like any of the other b series shifter bushing kit, there are 3 locations the bushes go.
1) The 2 circular bushes go on the end of the shift linkage closest to the gearbox (next to the 'bitch pin')
2) The bush with 2 holes goes underneath the shifter and bolts the chassis (just above the exhaust)
3) The last one that is mushroomed goes on the shifter itself, on the ball of it (about 1/3 of the way up it)
