I have been rebuilding my gearbox, the 3rd and 4th synchro gear teeth are badly bruised.
The synchro is a suffix "c" but the rest of the gears are suffix "d", I think the waisted teeth on the pinion may have done this damage, but I'm not sure, any ideas.

And also are selectors for suffix "c" and "d" the same or were they modified?
p.s. I will take a photo of the synchro and try to post it on the Forum.
Thankyou.

It might be worth having a look ar workshop manual page 37-20 which talks about changes to gearbox’s and what to do when replacing some bits , the parts manual suggests reverse selector shaft changes after 79 but the others don’t

I spent some time trying to work this out when my 3/4 syncho failed. In the end I bought the mating gears so I got a set of the same type. Mine was a non-syncho S2A
