I accidently dremelled off my motor end caps that are plastic and press on each end for the rubber band to run around. I need both of them. They were so dirty that I just assumed they were metal like the other band drive shafts and wrecked them trying to clean. Can't find any with a search. Would anybody have a couple of these? Here's a few pics of what I need. It's a shame I didn't see they were plastic. It's really a nice old Athearn. In the pictures, you see my attempts at repairing each of them. That's why they look different than original.
