Did mine as well, in fact I cut 4 holes on the underside and used nut and bolt setup, 4 small bits of UCote and you will never see it.
Never liked the aluminum tapped stuff as disimilar metals dont get along.
Gear is now as strong as it will get with no added weight plus its easier to tighten fully.
If you use a cannister the center ones need to be button head types.
Really does land light.
This is a good way to go. On the prototypes I did it this way because I did not realize the gear was tapped. He's right about disimilar metals as well.
If you don't want to do that, just drill the holes in the brackets a little larger and use a washer.
This is one of those things that is very difficult to get right in a factory build.
