Thanks everyone. I guess I'll try Jake's suggestion first, but when I searched McMaster's I see all kinds of bearings, but not sure of the exact description of the bearings on the car. I'm guessing they're thrust bearings of some kind.
The curved track sounds ideal, but not sure how to pull that one off. Never welded aluminum either.
Any help on the exact type of bearing would be cool.
Thanks
Barry
Search for "Torlon Balls"...not sure if this link will work correctly. I ~think~ the standard Harken traveler uses 3/16" balls - but I recommend you measure them before ordering.
