I think all we need is a hard plastic 32T gear to run with the stock 29T and it would last for a LONG time and be cheap and easy to replace because it's the top gear. My $3.50 47T plastic spur has lasted for 6 months and is showing no signs of giving in.
Pics of my new tranny. Three magnets that I had in my parts bin. One is under the gear wedged beneath the bearing holder. Just have to wait for the top gear to come in.
