I couldn't get the dowel pins out of the old cams and damaged them in the process. From what I've measured, it looks they are like M4x15. I can find them online if I buy 100, but I just need 2. The one machine shop I tried wasn't helpful. I tried CarQuest and they did not have metric sizes. Looking at the Mazda parts fiche, the pins do not show up. Does anyone have suggestions?
