Just shave down the width a bit then. Or buy a RCM idler if Mike has them still.

If you purchase a RCM idler it'll be the last idler you buy period. No mods,inexpensive and worry free.

Shaving down the 3996X isn't as easy as that (I don't think). If it's wider then I'm guessing the bearing seats would also need milled out to make up for the narrower gear or else the bearing would stick out.

I've already spoke with Mike about getting an idler and it's hard telling when they'll be in stock again. With the new 3905 trans out people aren't as interested in beefing up the older 3906.

I'm going to pick up a 3996X idler for my old trans since they're only $5. Since I converted my trans to single speed I'm thinking I should have room to fit the stock 3996X idler in there somehow. There is a fork style plastic spacer in there that separates the idlers from each other when it's a two speed so there should be some room I can make there.
