iTrader: (2)

Are the (two) idler gears in the 3906 2spd identical? Ordering all my parts for my "bulletproof" tranny and I skipped across a few threads on this and that about how they are different sizes, 3905 won't fit etc... Little help guys?? Tryin to get my parts stock piled before I head back home...

Ordering these: assuming they fit??
