I have discovered split axle gears on my doodlebug.  Can I get replacement drive wheelsets with gears or even a complete drive truck?

Figured it out. Difficult, but do-able. Thanks.

Aw, c'mon. NOBODY knows how to get the cab off? That's very surprising.  Next comes dynamite!

Have new GP9 w/DCC. Have removed shell, but need to remove cab to re-install windows. Cannot figure out how to detach cab from body. Please help.
