Just flywheel effect, is needed. A bit of weight at the very edge of the disc.
 A few small weights tucked right inside the flange where the ring gear sits might be all you need. I added 8 short TIG beads between the ring gear and that flange, because a missed shift without a rev limiter shucks off the ring gear, and just about cuts the bell housing into two pieces. Not likely with a prop installed, but you can bolt on stacks of washers to run for a few seconds to see if that is a cure, if you would rather not weld on the flex plate.
 
Hi Lynn,
 
I'd have to look at it in person, but it appears from pics that I could easily add several large washers, plus the longer bolts that would be required, to each of the 4 holes that bolt the flexplate to the drive dampener plate.  This is pretty close to the outside of the flexplate, so it's probably worth a try.  I'll make a note to measure the bolts, and look at the space available, next time I'm by the hanger.  
 
Thanks,
Rusty (50/50 for posts appearing today)
