Thank you for the responses. But here why I'm getting confused:
What I have now, without the bashguard, the nut/sleeves are 10mm in diameter. The bolts are 8mm in diameter. And the holes in the CRs and spider are 10.1mm in diameter. The nut/sleeve (could also be called a bearing) sticks all the way through to the outside CR up to about 1mm short of the outer surface. Therefore all the hole surfaces are riding on the nut/sleeve.
If I use a longer bolt (about 6mm) without a corresponding longer nut/sleeve when I install the BG and spacer, there will be 2.1mm of open space between the bolt and the sides of the hole. That will allow play in the BG and it seems like it will slide around.
So, on is this not important on a bike? On a car, it would be. Or does it not matter with a BG?
Again, thanks for the comments.
Did you read what I posted immediately above? It says the same thing. What do you mean by "ground down"? This a a very straight forward use of a bolt and nut to fasten a bunch of parts together. Don't complicate it.
Hillrider: Well this wouldn't be the first time I "complicated" something by over-thinking it!
