No, JJohn.  New to me.

Honestly it looks familiar.   I have check all my photos of the steering components, transmission, and drive train.  Didn't see anything with only three prongs.  Have you checked all your suspension points.  I have newer leaf spring shackles then the original ?   Sorry wish I could be more helpful.  I'll keep looking but if you find out where it goes please let us know.

From your picture it looks like that is a nut on a cylinder head stud?  If so it must be something that someone used to replace a missing nut.  There is nothing like it on my 30-U.

No, I just put the nut there for the picture..
thanks for the help

Did you check all the nuts on the driveshaft disks.  I had two different size castle nuts on my disks.  They fit the same size bolt but use different wrench sizes and may have been where I might have seen this odd castle nut.  Over the years these things get replaced and usually with whatever is lying around the shop.  Just saying.

Are you sure it's from your car? I've rebuilt a lot of 1960's MOPAR front suspensions and that looks like a factory installed ball joint nut. I save them because the wide spacing of the castellations come in handy sometime.
