Question. Were is the pivot? The Tremic is set up for a cable "pull" system not a linkage push set up. If you are using an early model fork with a pivot on the slave side, pushing from the engine side like the picture shown above , than yes they are different in length. If the rod is off center now that is not good to start with. For the best set up the push rod needs to push very close to straight on or it can bind the piston in the slave bore or cause the rod to rub the inside of the bore.
If you take a look at the picture above you can see the rod is nice and straight. The only problem or thing that may be a problem down the road is the slave looks a bit on the short side. If the system is set up correctly the bearing should not contact the clutch fingers. The early style bearings do not do well if they ride on the fingers.
Isn't setting up kit cars fun!!!
