I have a block that fits down over the alignment pins just like a limb. It has a drill bushing in it that keeps the tap in alignment.
For those that use the bolt as an alignment, I would think it would be critical that it were straight.
For those with 2 alignment pins and an oversized hole, not so important. The conical seat of the bezel allows for slight alignment issues.
I prefer the 2 alignment pins and oversized hole method. Keeps the finish from wearing inside the hole as you run the bolt in and out.
