HI Goldseeker,
Yes, is the short answer!!
Can you confirm that your gearbox casing has 2 tapped holes for the index plunger?
It is fitted underneath for the STD box camplate and on top on the RRT2 (fitted with reverse plate)
When you fit the std plate you will have to swop the index plunger location
The STD gearbox casing is not normally drilled and tapped for the reverse plate
You will most likely have to remove the gearbox to perform the change, the selector fork rod is held in by a grubscrew at the sprocket side of the gearbox
