Anyone buy aftermarket ring and pinion gears recently?
 

Just curious if anyone has bought a ring and pinion set from Rotary Performance or another vendor in 4.33, 4.50, or 4.77 ratio recently.

What I'm looking for is the overall length of the pinion gear, the length of the shaft from the back side of the gear teeth to the end of the shaft, the diameter of the pinion gear shaft behind the gear "head", and pictures if you have them.

I'm curious about these measurements since all three model years (1993-1995) share the same part numbers for MT and AT gear sets according to the Mazda part breakdown files, and no aftermarket gear vendor that I've seen lists separate part numbers for the FD by model year for aftermarket ring and pinion sets.

I'm trying to eliminate any possibility that there was any variance between the years to be 100% sure that a gear set cut for one will work in all others.

Thanks!
