Gama Goat Drive Shaft?

I also posted this under “Strange Part”. I think I’ve got these narrowed down to Gama Goat drive shafts. Fairly certain they’re made by Rockwell. The coupling end of the assembly is physically identical to parts in the M561 -20P and -34P parts manuals. The stumbling block I’m hitting now is part numbers. These shafts (5 each) are used and the only markings are L6N72F and L6N67F. After a thorough search of both TM’s, these numbers just don’t match anything in the books. Pictures attached:

It looks like a part of the steering between the tractor and the carrier. The diameter is to small for the drive shafts.
