Funny how things happen. When looking for the dropped accelorator pump connector link mentioned above, I found that my fuel pump pivot shaft was working its way out, with over an inch of it sticking out of it's bore! In the search for the missing link, I removed an aftermarket aluminum bodied fuel filter that someone had bolted to the inner fender at some point. As I removed the filter, I turned it over to check it out, and "clink", I heard the connector link drop! Yay! So that was resolved, carb reassembled, and the car back to its previous state.

I decided I should probably go ahead and change the oil and filter. For whatever reason, I assumed the oil pump was the oil filter housing - yet another boneheaded move. Since I had the pump out, I decided I'd clean and inspect it. Quite a bit of goop, gunk, and even some chunks, but overall very little wear (to my "untrained" eye, at least). However, I found that the pin holding the drive gear to the shaft was broken! The two remaining pieces look to each be about 1/3 the original length of the pin, so it stands to reason the grit was the other 1/3 of the pin having been ground up. I'm lucky I had oil pressure all this time, and once again a boneheaded move turned out to be fortuitous!

Now to the questions: Is this a common failure item? Where can I find a replacement?

At first I was tempted to throw in a roll pin, but I question the quality of the standard "variety pack" roll pins I have on hand. Considering the original was solid steel, I doubt a hollow roll pin would hold up, and this is obviously a critical component - if it fails entirely, the engine has no oil pressure!

The pin is pictured in the parts manual, plate #93, but has no associated part number, leading me to believe it's a common, universal type pin.

Does anyone know what these types of pins are called? The remaining pieces appear to have three longitudinal groves equally spaced around the circumfrence, and extending the length of the pin...diameter is .125".

Thank you all for any insight!
