Cam Button Question.

[Enbloc]

I've mocked up my early style dizzy on my late engine with the cam button installed. With both the cam and dizzy engaged in the button the dizzy sits about 1/8" proud of the timing cover.

I've noticed the button has about 1/4-3/8" deep slot with the dizzy tang being only around 1/8" deep.

Does the button have to be ground down to obtain the correct fit?

Thanks.

The picture is out of a Ford shop manual. How does the button you have compare?

Maybe you don't need the button, not all engines do?? ....OLD.....BILL
