Found some very small pieces of metal in the front sump of the oil pan (351C in a fox body)actally they were against the magnetic drain plug. Pulled MSD distributor and sure enough they were from the roll pin holding the bronze gear on. The gear hadn't spun on the shaft but it had been working against the pin. I have another roll pin from the old steel gear, but wonder if a solid pin would be better. Also wondering if I put something around the gear to retain pin pieces if it ever would break again. Thinking something like a wire tie, but don't think it will hold up to the hot oil and rpms, any ideas? Oh, and by the way, think it started shearing the last time I raced the car, it was in the 40s that morning and I had pretty thick oil in it.

According to Animal Jim, if you go to the next size up (3/16) and use a spiral roll pin, you won't have this trouble.I have yet to find a place to buy them, i might have to call AJ. Another trick is to use two roll pins at 90* to each other. ------------------

Oh, BTW, the hole in the new dizzy gears may or may not be at the right height, specially if they are only drilled on one side. The distance between the bottom of the gear and I think, the machined base of the dizzy that sits on the block, is 4.031"-4.038". If this is over this spec, your dizzy gear will be binding against the block when the dizzy is locked down.more info here..... http://groups.msn.com/64Fairlane/64fairlane.msnw?action=ShowPhoto&PhotoID=15
