ok so i just rebuilt my tranny and i bought a new spur gear because the one i had was stripped. the guy at my lhs said that the 87t one would fit on my rc10gt. i have been running either a 66 or a 64 and the 87 seemed interesting, so i took it home and rebuilt the tranny and when i went to put the spur gear on it was way to small. do i have to do something to make it fit or is it just the wrong one.???? part number is 9654.????????
help please. also what size spur gears do they make for these bad boys? and does anyone have any experience with running a metal spur gear?
