R32 GTR synchro needs replacing
so in my r32 gtr when changing from 3rd to 4th over 60 km it crunches so im guessing the synchro is gone i am planning on pulling the gearbox and replacing the synchro, i have a friend who can do it for me but he has never done a 32 sychro replacement,
anything to look out for or tips
also where would you recommend buying the synchros from? do they have a part name?
thanks,
