015/016 Monoball shift bushing replacement

[John Cody Forbes]

Yeah the lever with the ball on it is cake. Just grind away the back side of the shaft for the ball that is peened on then you can drive the ball out with a punch. This leaves a perfect hole ready to run a 8x1.25mm tap through, voilà, done.

Seems there's enough interest to get going on this. I shal order some more monoballs/spherical bearings tomorrow evening. Because I'm working a more than full time job mon-fri this project will be 80% a weekend thing. Expect an update in about 2 weeks (the new style bearing won't be here until next week and then that following weekend I'll be able to make the bushings for it). I'll test it and make sure it's perfect, then put together about 10 kits and give my paypal address ;-).

>> So the big ball socket shifter bushing on one of my 5ktq's disintegrated a few weeks ago. As some of you may know, this bushing is NLA. 034 has some, but says it's a finite supply. I didn't want to be slaved in the future to ordering one from California or stuck if/when they run out, so I decided to improve the shifter while using a readily available part.

It would include a modified lever for the transmission (would need to have your old one as I only have one spare), the bushing the holds the monoball in the shift linkage, the monoball, the inner sleeve/spacer, and the bolt. Installation does not require removing the linkage from the car, my assembly drops right in where the stock bushing used to live.
