I just pulled a south bend out of my truck which put this same 'groove' in the 13" flywheel purchased with the kit (disk, flywheel, pressure plate, throwout)... truck only pulls 5K of skiboat and driveability was much better with the stock unit. Beyond the hopping in reverse, all of the driveline action resulted in multiple leaks from my transfer case... very happy to take some pics if anybody's interested...
