you are better off just buying a hole new gear box, spare gears are always handy i used to strip gears in the trannys on my savages for a past time. in my personal opinion the 2 speed trannys are better. time you hit 3rd gear you nearly out of space even ajusting the gears for a shorter change. i will ask me mate if he has a 3 speed tranny in his big box of savage bits if you cant find any thing.
