This is my first request on the forum, happy to be here. I have a Lionel 6-18870 Pennsylvania GP-9 with TMCC and a Pulmor motor. The nylon drive gear is partially stripped, most likely from years of operation. The Lionel website lists part cs-6308332078-p Gear shaft assembly as an option to replace the worn nylon gear, but is out of stock. Can I use the postwar part 2328-78 Gear Assembly with Bushings instead? The parts look the same and I assume the teeth will line up, but want to make sure before I take it apart.
