Congrats to getting your engine all back together :beer:
Did you center the clutch disk on the flywheel? If it's not centered the "teeth" won't line up. You can get a cheap plastic alignment tool for it or make one out of wood. It would require loosening all the pressure plate bolts (quarter turn at a time), centering the disk, retorque the pressure plate bolts (quarter turn each in cross pattern until pressure plate seats on flywheel then torque to spec in stages so you don't bend the pressure plate) . Best of luck - John
