I don't see any cross reference for that part number. Measure the outside and inside diameters and you should be able to get a good parts store to find you a replacement.
Ill take a look. Thank you! Cant actually bring it in because its still on the trailer. The hubs and grease looked good so we left it alone until we find the parts. Its a 1960's scamper with non standard hubs... according to modern standards anyhow.
