Neil, Can I see a sketch of how it all fits together front to back?

Main cost is the splined drive block so that it matches up with Tracy's splined input shaft. The photo shows the 2 parts of the unit, spacer and splined cushion drive, which bolt direct onto the e shaft with the normal flexplate in between. Uses the normal flexplate with no strain whatever on the flexplate. Your money and your decision!!
