Easy bigger advance limiter bushing for MSD distributor

NeeMa said

I also machined my own limiter bushings.

Biggest i could install is 0.393“ (10mm)
Result is 14 degrees.

So what diameter did you use to get 10 degrees?

I'm not sure what dismeter he used but they have to be filed flat on 2 opposong sides to move freely .I'll check my stuff in the garage to see if they got unpacked after the move .
