Pertronix still uses the plastic magnetic wheel on several of their current modles.

from what Im seeing on there site the pickup (?) has a lot # stamped on it so they should be able to dertermin if they had a bad production run and do a recal. Not realy seeing anythi g stamped on the ring though.

to further compound the issue some Ignitor II's show a wheel while others do not.

Now im wondering did mine come with a wheel? Im in KC and the truck is in arkansas. Next ti.e I go down I will get pics and verify which one I have.
