Hi out there, Recently acquired and bringing back to life a 68 California GS. In the process of replacing some transmission seals, it appears the drive shaft is a bit too long for the application. Haven't a clue as to how that happened or why, just that its an issue now. The bushing in the output shaft housing is also wiped out (due to the prop shaft mis-match?). The transmission is indeed a Buick ST-300 2-speed. It is very smooth and shifts nicely. The output shaft housing bolted to the rear of the transmission (it also contains the speedo gear) looks suspiciously clean compared to the transmission case. Were there different housings made for this transmission? The technicians want to have a pro-transmission/drive line shop shorten the driveshaft and rebalance it to bring everything back into harmony. Is there anything I don't understand here or is it quite possible a different replacement drive shaft was installed in the car for whatever reason. I am unable to contact the oriiginal owner. Thanks Tonino
