My tranny locked up in 3rd gear at Grattan Raceway in MI. Had to drive it back to IN in 3rd. Interesting driving experience. MazdaSpeed Motorsports has everything I need but the 3rd to 4th Fork Part#1650-17-404 If anyone has one their willing to sell or a good used one please post response. I can also use the shaft for the same Part#8086-17-421 but I can probably get a machine shop to make me one. Any other suggestions would be appreciated.

is that the one with the bolts? or do you have a later trans with the roll pins.
if you have a later trans, i bet a later fork would work, they cant be that different. shaft too.
ive als heard you can weld the forks, but they are iron, so maybe its hard?
