I have already dissasembled the spare GSR tranny i have from a froend that grenaded the diff at the track. Well further damage is the pinion gear on the main shaft is also missing teeth.
My question is the main shaft the same on a B16, B18 trannies? also do you have to change anything out besides the LS 5th(like syncros etc???) Everything else looks good with the tranny. I have been researching in the helms i have.

If anyone has a LS 5th or a GSR main shaft let me know how much you might want for it.
