V6 jimmy,
A few years ago, I think I got that bushing either from Jim Carter or Chevs of the 40s. It looks like neither company lists these anymore. Nonetheless, while the Steele part is expensive, it is molded into the steel "seat" (the one I got had to be pressed in and might not have been as tight as the Steele product).
I hope I am thinking of the same part you are - please post a picture, if you are able.
Good luck,
Tim
