MM sold that part of the business, I am pretty sure to AutoSolutions. You can
order it through Bav Auto.
It replaces both bushings, the nylon ball in the shifter console, and the cap
that attaches to the tranny (as well as the shift lever itself).
I recently installed one while doing an upgrade to a MM 2.9l stroker (1990
325i). The shifter is much tighter now.

Yes, everything that moves is replaced.

Obviously, a new pilot bearing, throwout (release) bearing, etc. You might want
to check the rear main crankshaft seal. Mine leaked for some time. Also check
the tranny seals and the flexible coupling (guibo) and center bearing.
My stroker project happened sooner than I had wanted because my throwout bearing
seized (clutch disk itself looks almost new) after almost 200K miles. I plan to
post my story on the whole upgrade soon.
1990 325i 2.9l stroker (awesome)
