I think that is a Harley one and the screw part of it will be too short. The mag on Chris's Streamline takes one that is right about 1-1/2" long. The Harley is more like 7/8".
Call them and see though. They might have something that will fit.

It's probably metric, just some non-standard pitch. The Bosch mags on Harleys use some weird threads too. You might have luck at Competition Dist. and there are some guys that specialize in magnetos that might have something.

I need the spring-thing screw that holds the points cover on my KJ's the FF4 magneto.

The previous owner of my KJ had the advance/retard bellcrank backwards, and I finally got around to installing it the right way. After re-positioning the band on the adv/ret ring on the mag, adjusting the points, I was tightening down the spring-thing screw that holds the bakelite points cover on - and the darn thing broke off.

I got the broken screw end out of the mag no problem. Went to the parts store with one of the regular flathead screws only to find that it is neither American nor Metric thread. What the heck kind of thread is it? Who has these screws? And does anyone reproduce, or have a spare, of the spring-thing?

It's 70 degrees today in Virginia, and I was ready to go for a ride, but here I sit so broken hearted...
