There are plenty of excellent tight shifters around, as well as machined bushings. No need to step up to a different transaxle to fix it."Sloppy" is VW standard. Precision is not applicable in a T1 transaxle. If you want more "feel" you'll need to step up to a Porsche 993 or a Quaife.
You think its worth the effort?? the rubber boot covers most of the lever. Only a small section is exposed.Huge improvement. My only suggestion would be to polish the shifter so that it matches chrome accents of the handle.
