steam driver replacement

have just gotten back into HO w/bachmann 2-8-0 from wife. have a number of older ihc pacific/mikes and would like to change out driver to scale flange any suggestions

Greenway and Bowser sell driver sets that may be useful.

The websites are.

www.bowser-trains.com
www.greenway-products.com

Alvie.

You can also try www.bachmanntrains.com click on United States, then on the bottom of that page click on "ASK BACH MAN

Without wishing to unduly alarm you, the replacement of older IHC/Mehano or Rivarossi drivers is a daunting task, usually refused by experienced locomotive rebuiders as either not feasible at all, or too expensive to be considered. “Standard” North American driver-axle-gear combinations, like Bowser are great, but not for plastic European locomotives…the construction is substantially different.
If you deal at a local hobby shop, ask who does their locomotive repairs [if anyone], and perhaps you can speak with that person.
You might want try this question on a couple of other forums also, as there will be some disagreement with my post here.
