So the short answer is replace the distributor for the worn gear.

I'm loathe to replace any major OEM parts with Chinese replacements that I don't have to. They tend to have tolerance problems with the final machining of the case castings that place the distributor too deep or too shallow. If there's not too much side play in the distributor shaft I'd replace the driven gear on the end of the distributor. If it's possible to re-bush the OEM casting to tighten up the distributor shaft I'd go that route before installing a dubious quality Chinese part.

I'd take a look at the cam gear (drive gear) with a bore scope as well.
The driven gear end play probably needs to be set with shims after 20-30 years of service. Similar to rebuilding a big cap HEI without the additional fun of re-working the advance mechanisms.
