I had a distributor that had the Duraspark conversion by Dave's HEI in Nevada. He drills and taps the reluctor in between 2 of the arms of the star and holds it in place with a set screw. about #8-32tpi.

Looked around and don't have a roll pin to measure.

The roll pin is about 1/16 - 3/64 - get a few sizes at the hardware store and snip them down to length. There isn't any torque to deliver  - it just needs to clamp itself on the shaft, down against the stop.

The slots are 180° apart on the shiney replacement reluctors I get at NAPA - the gadget won't care which one you use.

If you get in a bind for info - PM me and I'll help you any way I can.

Dont know what the size is, but you might get lucky at a Ford dealer. We used to lose them all the time and have to get one from parts. Maybe one in your area has one hidden away somewhere.

the roll pin got damaged for the reluctor. anybody know what size to replace it with? The reluctor has 2 slots so which one do you use?

Thanks,Kenny
