@Tom D. posted:Greendog -- Using the China drive would make it easier since the side frames aren't bearing surfaces. I could never find a drive like that with the correct wheel base, but they exist from looking at these pictures.
Good luck!
Tom, Greendog, that's a good question, about three years ago I bought six powered chassis off ebay and the trucks that I used for the C-Liner mod were Lionel Alco AAR trucks but I am not sure what the loco was that went with that chassis. Another issue I pulled all the trucks off the stamped frames when they arrived so I am not absolutely sure what the frame I used was from. If I had to guess I would guess that both the trucks and frame were Lionel. Something else that may work is Weaver had some locos with china drives in them that also had Alco AAR type trucks and if I had to bet I would bet they have the right wheelbase for the Rivarossi FM side frames because the Weaver chain drive AAR trucks are the correct wheel base (photo). Before I found the china drives I considered sanding the detail off a Weaver AAR side frame and gluing the C Liner frames over them. j
