Does anyone have any advice on how to go about rebuilding, or having re-built, an original 50-something year old Ford distributor?

This is an original 1963 Ford distributor for a 260 V-8 with a Ford-O-Matic.

I looked around on the internet for a re-build kit and did not find one.
I also looked for shops that rebuild distributors and was left confused.

Has anyone had a distributor rebuilt and were you pleased with the result?

What shop did you use?

Thanks, Dennis.
