David,

Is it possible for you to measure = the wear mark on the RD1-X drive input shaft splines to see if there is any = indication that the RD1-X adapter plate has moved in a forward/back linear = fashion? If there is, then wherever that is coming from is the problem. It is = either flex in the flex plate, or end play in the input = shaft.

Everybody is trying to fix flex in = the flexplate, but I don’t think we have definitely ruled out end play = in the input shaft yet.
