First, I apologize for not having the Lionel product #. This is an early conventional one. Does anyone know if I can source one of these small plastic inserts that the trailing truck axles ride in? The plastic is broken on top and the axle pops out after a short run. If not i can just rebuild with JB weld and redrill the axle hole. Also, are the small plastic pieces just friction fit into the diecast truck? I used a pick set but couldn't seem to pry it out with normal effort. Thanks and Merry Christmas!
