Must admit that i did not look all the specs up.
But the design and the material that the rubber dampner itself is made of, seems good and strong with new technology in the rubber casting.

>>> A plan could be, should the RD1C spines parts strength be questionable, leave it riveted to the 0.2inch thick aluminium damper plate. Cut/machine that plate down to the same circumference as the spined part, approx 5 inch, and Drill the 6 x 10mm holes and attach direct to the EShaft through the spacer machined to correct size.

The OD measurement of my spacer is approx. 5 inches, so it would appear possible to mount tracy,s splined drive shaft plate direct to the E shaft with the 6 x 10mm bolts and spaced out with my spacer which may have to be adjusted for height – a simple lathe job. This as well known eliminates any ‘damping” in the drive line.
