I had a distributor with a worn out
top bushing. This service part is NLA, so I purchased some 10mm inside diameter oil brass bushings. Had the outside diameter turned down to 14.95mm (same as the worn original) and beveled one edge to copy the OEM bushing. I have 4 spares, and will happily part with 3 of these to anyone who wants one for their car or project. See images. Beer money accepted.
