Oh dang, I have the * key thickness and use drill bit shanks to set mechanical in those distributors.

It should run a bunch better

Wish to 'ell I'd thought of that...................You have a chart you can post the dimensions?

This is what I have. I did read somewhere that the 16 was really 14, 18 really 16.

12 0.125
14 0.140
16 0.155
18 0.170
20 0.185
22 0.205

Take it for what it's worth and always verify!
