magnetodistributor gear roll pin size or better quality

I am running a msd20 the distributor gear roll pin is getting work hardened where the shaft meets the gear, ready to break more than likely. Is there a good quality pin available? Or drill oversize to ??
It drives the oil pump also.

That should be a spiral pin,tougher than a roll pin. I would just replace it with a new spiral if you have concerns about the current one.

You may want to take a look at what Paul Kane said in post #3 while you have it apart.

It looks like some of the spec.'s in the old 460 Ford link got lost. Below is a Ford Data Sheet, that may help.
