Just put 496/5 speed in 69ss chevelle, removed 396/4 speed. Used keisler package tranny,pilot bearing,t.o.bearing, and clutch. Reused bell, clutch fork,z bar, p-plate and 6" adjustment rod. Problem when I start car in neutral, push clutch in all the way and attempt to put in 1st gear the car makes no gear grinding noise but inches forward but clutch is still down to floor will not go into gear. Do I need 7.25" rod and adjust more?
