QuietLine drive lines have wear throughout the line! When updating this set up you must carefully examine every component. I found it is imperative to replace not only the drive shaft but the couplings, spirol pins, bearings and flex discs. Since you are installing new mounts have you performed the cradle mod? Have you examined the mounting surfaces on the oil pan to insure a solid fit? Pay close attention to the clutch release arm and the bracket it is mounted to. I would suggest replacing the three pin driver with an older version. Replace the clutch disc with older version and disregard the flex disc...they usually fatigue and crack. Replace the clutch release bearing too! Do it right..do it once! It gets expensive but repaired properly, it should give you many years of good, trouble free service.
