Often wondered what that was myself ! Only thing I can deduce is that it neutralize exhaust vibrations an harmonics .

I think thats whats called a vibration damper.
something to do with the tailshaft of a 904 tranny.
the 727 didnt have them. I read something about it
years ago. Can't remember exactly why. It has to be
in some Mopar archives somewhere.
