I am asking for your help. I have a 1963 4 Speed. The clutch disengages as it should, but when you start moving, the gear will not engage unless you press the clutch to the very limit. Clutch shakes also a little. I conclude that the clutch comes off at an angle, allowing the gearbox to spin a little along with it. I have restored the pedals, New Clutch Plate, new Pressure Plate and Clutch Cover. The Releash Shaft has been restored and all the bushings and likewise the Suport Brancet. Whole Clutch Pedal Travel is OK. New Pressure Bearing. Fly wheel looks fine (have not measured). The only thing left is Housing, which might have wrong alignment? Could this be the reason? Something else?
