Joe, There is another way which is my cushion drive (attached) which will cost approx $500 USD plus freight with the current exchange rate. 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!!

Hi Joe, I believe there are two ways you can go, though I don't have part numbers or exact details for you:
1) Tracy's Method: Use an aluminum flywheel directly, including the center spline coupling - this eliminates the damper plate and the need to drill holes. The catch is the spline does not match the original RD1-C prop shaft spline.
2) Dave Leonard's Method: Use an aluminum flywheel, no center spline, mount the damper plate, remove material from one face to adjust ring gear position relative to starter.
A quick search of the list should get you more info as it was discussed lately ...

I have been looking at various flywheels for possible candidate replacement.
I thought the aluminum units would provide the least amount of weight gain.
I noticed that there are a lot of holes in these units including the replaceable friction area with many screw holes.
I was under the impression that the holes in the flexplate promoted stress cracks.
These flywheels however may have sufficient material to counteract the stress potential.
Can someone provide a brand or part number that is acceptable?
I believe that the additional machining to modify one of these flywheels is the holes for the torsional damper.
Thanks for any help.
