I made another small improvement to my shift linkage. The end of the shift rod has a 1/2" 6061-T6 right angle piece that functions to rotate the transaxle shaft and push it in & out. I used an aircraft counterbore to make a 3/4" hole for the 0.750" shift rod. It turned out the hole was bored about 0.020" oversize so I used some 1/4-28 set screws to secure it to the shaft. This worked OK but I thought that I could reduce the chance of rocking back and forth when shifting by adding a second thickness to it. By bolting the two pieces together with a 5/16-24 Ti bolt, the two pieces are held rigidly together. So far so good...

Neil, you could put some divots in your rod for the 1/4 set screws to prevent any slipping/rocking issues.

Yes, I plan to do that when everything is adjusted to its final position. Here is what I'll do (but without the hole). Set screws don't bite into the Rockwell C60 surface of that shaft.
