Ive got a 1978 928 and im having the same problem with the shilft linkage. It turns out that the linkage cup is all wore out on mine also. Ive got it at the shop (i dont have a lift) and they are not sure if they have to remove the whole torque tube assembly to get to it or not? Im curious how hard it was to replace both the front and back cups? If anybody knows anything about this, please call me at (509) 947-5016 or email me at
