I have a pair of Warn Lock O Matic hubs, that are NOS in the original boxes. I don't know what they fit. Information: it looks like M 15 E on the outside stamped into the lock / free handle. It has 19 splines and is 4 7/16" OD and 3 3/34" bolt circle. On the outside of the outer box it states model number SP2209H. These are in Mopar label boxes, copyright 1972.
