Replace with a used unit is one option. I bought several thru the years because I kept learning new things. Like the two tits on the points plate that are for the screwdriver and to use when adjusting dwell? These tits are really important. I had some worn out tits and all I can say is "never again". What a pain. I'd rather repair the cam felt.
Tiny nut and bolt, probably an M3? Maybe even smaller than that but it is repairable.
Never memorize something you can look up.
