[TR] What are these parts?

[Dennis Culligan]

   The attached photo shows parts that were shipped to me by mistake by the
Roadster Factory (they are shipping the ones I actually ordered next week,
so no worries).  Any idea what these are and what car they might be for?
They appear to be some type of bearing and are soft rubber on the inside and
hard metal on the outside.  I do not recognize them as anything I've seen on
my TR6.  Guesses anyone?
