Hi folks, been trying to identify the thread on the primary chaincase oil level screw as mine is shot (1960 super Meteor) and I need a helicoil.
I have a thread gauge and it says 22g which I assume is 22 teeth per inch? Making it 5/16 BSF?
Where do I go now to narrow down the thread so I can pick up a helicoil set please?

Thanks

Dave
