http://www.almabolt.com/pages/catalog/pins/springroll.htmSpring type roll pins are a good answer here, but like Jerry eludes to, not something I would feel good about in the long run, but this website talks about putting a roll pin inside a roll pin. I just rebuilt 2 distributors using this method and the gear is tight, and I cant imagine with the force pounding the 2nd one in, anything ever happening concerning that gear again.
