Here's a picture of my GTS after a I fixed my TC bearings and with a new transaxle from 928 international. Photo was taken with all parts adjusted to factory spec. and TB @ 0.25 mm.
After this Loctite 290 was applied, because back than the was no other cost effective solution. Mileage was about 100 k in 2005, today at 186 k with no change in TB tolerance.
