True advice already posted. Regarding the pinch bolts and torque, reference my driveshaft failure experience. It is critical the threads of the shaft's yokes (or "collars") are all in perfect condition. I suggest new fasteners (pinch bolts), make sure they each thread in by hand to avoid any cross-threading which is destructive, use a thread locking compound, torque in steps and back and forth repeatedly between the two pinch bolts until both are secure. Applying a compression to the split yokes may be required to allow the fastener to line up truly with the threaded hole on the opposite side. After my failure, I took the risk of slightly increasing the torque. I cannot say this is best, just what I did over the worry of another failure. Apply "witness marks" and monitor for loosening for 400-500 miles/ 650-800 km.
