| RE: Distributor Gear pin |

It's standard practice for distributor rebuilders to use a rolled spring pin in place of the original solid pin when assembling the distributor gear.
These rolled pins are not strong enough to reliably work with a HV or HP oil pump. They often shear.
You need to see about getting a solid pin installed into your distributor. It should NOT be a hardened steel pin, but other than that I'm not sure what type of steel it's supposed to be made of.
If you have a stock (skinny) oil pump drive shaft, it's probably working a bit harder than it should, too. You might want to inspect it to see if it's twisted at all - they're supposed to be a straight hex shape, not a barber-pole twisted hex. A HP shaft is a requirement when you run a HV or HP pump.
You may not be able to access your drive shaft without removing the oil pan, as yanking it through the distributor hole might cause it's retaining clip to fall into the pan. This is not a disaster, but I just hate knowing there's an extra chunk of loose metal sitting in my engine, even if it is in a relatively inert location. If the drive pin follows the distributor up when you pull it, the previous builder didn't install the clip. This is fine, too, but I seem to recall you stand the chance of dropping the whole shaft into the pan if you don't handle it carefully.
I hope you retrieved the remains of the sheared pin OK.
