Harmonic pulsation / Vibration?????????

i've had the same problem for years. finally have started to attack it incrementally. i just changed to a poly rear tranny mount and will check driveline balance next. after that i'll check pinion angle.
something i didn't know before researching was that the tranny yoke and the pinion yoke must be clocked differently, something i make sure of now when re-installing the shaft.

How does one check the "clocking" ? That has promise. But I thought there was really only two ways to put each yoke on and that it made no diff. ??

I was looking at the "rotor phasing" post again and still cant figure that out.....the line on the rotor as viewed thru a hole in the cap would just show the timing of the rotor going past the wire tower and when it fires...which is what you re adjusting when you adjust timing. How is this different from "clocking" the rotor?
