An interchangable spigot is probably the easiest way. You might be able to have a 97mm spigot on one side and a 99mm on the other side and flip the jig over.
I've never had to fix one of those threads, yet. Didn't they get fixed, drilled and all, free hand years ago?

It is very do-able to drill by hand. If you are skilled and lucky, the hole (and repaired stud) are nice and square. If you have an off-day, or marginal skills, the stud is wonky. I've seen poorly repaired studs fail and then you have one and only one chance to re-repair it. For the average or below-average home mechanic, it's better to have help, and the drilling jig probably boosts the chance of success.

True that, but some like the idea of making their own tools.
