I kinda get what your saying. Unfortunately I only have a dremel tool. But I did find some screws that fit not I need to just trim the screws and it should be good.Something else worth mentioning if it has an adjustable 510 pin, threads inside and outside to contend with.
I've been known to make a jig for things, squaring off the fence of a table-saw. I put the abrasive on the fence, and squared the jig by means of the adjustable miter of the tablesaw, by using the guide in the table-top.
If that makes sense!!
