Hi Neil,
I have not had to have this done but it appears that Frank might have found a replacement flywheel on eBay. I would think that the original part could be ground and a new ring attached but it might be less expensive if you could find a suitable replacement part. The 29 block was used for a number of years and I suspect that the flywheel didn't changed much. According to the Plymouth Master Parts List 28-33 both the Q & U had ring gears.
Ring gear Q Part# 319916
Ring gear U up to Y-201-PP US Built and All Canadian built Part# 303039
Ring gear U after Y-204-PP engine #U-89290 All US built, 30U, PA Part# 74455
I don't know why there were differences in the Ring Gear. Form and fit might be different but I would suspect that function would be the same Just my uninformed opinion.
Have you talked to a good machine shop ?
Good luck Chet...
