Hi folks, I really appreciate all of the comments feedback.
I realize that the easy thing to do is buy a new hinge (with door stop) or just the door stop by itself. At the moment all my interior hinges and door stops are the same. I've looked at door stops at Lowes/HD and they have similar ones, but not identical to what I need.
I was hoping to purchase 10 or so bushings so that as they wear out, I just replace the bushing rather than install a new style/design hinge or door stop. With the hinge ID being .23" I'd expect the OD to be close to .25 or quarter inch. I had assumed (potentially incorrectly) that this being a standard size, they would readily be available.
