Hi i was trying to put in my new clutch and i did it ok but when i took my drivetrain off I forgot which way was up. Can anyone tell me if there are anymarking or any way to tell. Thanks alot

 

I did a clutch on my 90 Z
if you are talking about the driveshaft it will only fit on one way, insert the one end into the transmission and the the back part that bold to the rear axle only fits one way.

Sorry I'm not sure what your talking about but if this is any help.

A few tips in changing a clutch clean the bell houseing,resurface flywheel, and replace the rear main engine oil seal.
