Yes. Part number 91688.

Get the parts catalog(ue) from Martin Robey. You can look up the part and see that both transmissions have the same part number for their respective clutch forks. Ergo, they use the same fork.

The fork pivot is different between the two if you go with part numbers, I don’t have access to the shifting forks right now and won’t for a few weeks but I’m almost positive that there is a difference with the forks as well, I believe the 5 speed is shorter.
Not trying to cause a problem here but I think it needs a bit more input.

The forks are identical according to the parts catalog part numbers and illustrations.

However, you are correct that the fulcrum pins are different (once again, according to the parts catalog). The pin part numbers are different, and the fulcrum pin for the 5 speed is shorter that the 4 speed's in the relevant diagrams.

Hey gang: just looked at my stock and they are the same. The main diff is the fulcrum stud for the 2 different bell housings.

Thanks for clearing that up Bruce, I was confusing the fork and pivot.
