@mkrazit
Have you had the mod done? any feedback? Would you have the source for the parts needed to do the mod?

Good news is I expect another modified shaft back by December which WILL be assembled into a rebuilt box w/ new bearings and syncros. I'll share details when I have that shaft back.

Thanks for @ mentioning to bring me back to this. I haven't formally reported back because I don't have a modified countershaft in-hand yet. The shop I'm using successfully modified a shaft, but that shaft had corrosion in the shaft gear teeth, thus I reassembled only to check clearances (no issue).

I just noticed something about your measurements above. Is there an issue with the curvature of the components against the flat measuring surface of the mike? I suspect so, at least if absolute precision is required of those measurements? Or is it a case of close enough for practical purposes?
For the OD it’s fine, but yes for the inside curves your absolutely right, it should be measured with a ball-anvil micrometer

So I have the countershaft back from being modified but have been occupied w/ OTM maintenance -- the reason I haven't updated. (Photos below showing machined and shot-peened shaft, hardened thrust washers, Spirolox retaining ring, and 4th gear w/ clearancing for wider thrust washers.) Next is this gearbox rebuild.
Team Rip Engineering in Kalamazoo, MI. Quality and price are great. Delivery? Shaft delivered to them 21OCT, I picked it up 22DEC. It takes a few days for them to modify the shaft and set thrust washer clearance -- many other priorities shoved this to the side. If more people sent their shafts to be modified, this might become more of a priority for them. PM me if you have further questions.
