There's an additional bushing in the rear of the shifter assembly that we
didn't replace when we did the short-throw shifter installation; we just
replaced that one today with the KartBoy
version, which seems to have given a bit more crispness to the end of the
throw, but nothing quite as dramatic as the main bushing and the shifter
replacement. One thing I did note, however: the stock bushing, after only
11,000 miles on the car, was already cracking and looking fairly sloppy.
Let's hear it for quality rubber OEM engineering. :-P
Installation of this one was a little more difficult; it would have been
much easier if I would have done it while I had the shifter out, as it
would have given quite a bit more room to move the lower rod around to line
up the bushing in place (both bolts are back behind the exhaust and
driveshaft, which made for a few cuts and contortions). Otherwise, it was
pretty straightforward, nothing someone couldn't do in their driveway with
12mm (OEM) and 1/2" (KartBoy) sockets and an extension or two (and maybe a
crow's-foot, which might have made reaching everything a little easier).
