Hi all.  I found my n-scale kit from when I grew up (mid 80's) and was excited to get it rolling again.  Unfortunately, the gears sandwiched between the wheels are all cracked so the wheels don't turn.  I have verified the motor itself is fine, but it just can't do it's job due to the cracked gears (it's hard to turn manually by hand past the cracks).    Does anyone supply these gears - they're labeled 9907 "Gears and Pin Set" on the spare parts list, and on the exploded view it's labeled as 9907-1.   Bachmann parts department verified they don't have a replacement, but I was hoping someone has come up with an aftermarket part that works.

I did buy a newer set to play with (McKinley Explorer), but I'd REALLY love to get this engine running again for nostalgia's sake.
