Does anyone have a source for drive wheel sets for a Hong Kong Lionel GS-4 by Bachmann?
I found them for the Bachmann brand  GS-4 on the front page of the Bachmann web site, but they do not fit the Lionel  version.

The Bachmann HO GS-4 has the driven gear on the #3 axle....the Lionel version has the driven gear on axle #4 and the gear is a different size....hence I cant switch the axle bushings from the new sets I have from axle 3 to axle 4.
I need 2 sets for the Lionel version.
  If anyone needs a set of these for a Bachman GS-4...I have a spare set.
