Sorry to hear your problems. A bronze gear is only needed with a billet steel camshaft.
It seems that every time I hear of a distributor drive pin failure, there was some kind of a "rebuild" involved?
The gears definitely need to be double pinned.
A lot of these replacement pins are coming out of $.99 roll pin assortments with absolutely no control of the quality of the pins.
Also because of the additional load on the drive pins as a result of thicker engine oil viscosity, I'm not a believer in it.
The slick 50 thickened your oil. In the future, don't bother. Run a 10-40 full synthetic like Mobil1. I just don't see where there is a need for 20-50 in this engine any more. Things have changed since 1970.
