Lots of photos, I know. Just want to make sure. I had to also grind down a bit one of the teeth in the disc Burton supplies where the screw goes cause it didn't line up 100% with the board and the screw wouldn't go in. Weird, can't be normal can it?
Looks good as far as I can tell. Look from the bottom of the board with the boots strapped in. That way you can see if there is any difference in heel and toe overhang. Try to get it centered, but if the binding leaves you a few mm one way or the other it's no big deal, you won't be able to feel it. Only worry if it's 3mm or more off center.
