Perfect! Thanks!
Kato sells a replacement truck for their bi-level cars.

It is a 41-NV-11 truck. Other cars may have used different trucks.
A 41-HL-11 were used on the C&NW cars.
Walthers offers a 41-N-11 but that may not be an exact match.

Hope that helps, Ed
Years ago I bought two HO scale CN&W bilevel commuter cars at a train show. They are made of wood, and look good except the metal trucks are too big and do not perform properly. I have no idea who made them, and would like to swap the trucks. I've looked at Walthers, but I'm not sure which truck is the right one. Can anyone help?
