Thank you all for the info. I did try to call parts line last Friday, but couldn't get threw. Will try again later. Have a few ideas on how to make part, just thought I would try to get the right piece. Good input on how to fab a part also. Once again, thank you for all of your replies. Joe S. Merry Christmas !!!!

I am trying to find the plastic pins that hold the piston arms onto the wheels ( not sure of the correct terminology). The item # on the box is 58616. It is the Blue Comet Atlantic City Express 4-6-0. Looked at web diagram and parts list and found a push pin, not sure if that is what I need. This pin is what holds the wheels on. My wife found this at a garage sale for $7.00, with a box of extra track. The set is in great shape, the engine runs except the arm come off of the wheels. Our grandson can't wait to run his new train.  Any help or advice is appreciated. Thanks,Joe
