They will come with all hardware necessary for installation. No driver though. Package includes 8 screws, 2 three hole mount disks, 2 four hole mount disks for non-burton boards or just one set of uni-disks for use on both burton and non-burton boards.
I found that it depends on different brands/models of boots. Most boots with the proper sized binding will fit fine. Although I have ran into a problem with mine where the capstrap didn't fit over the toe of my boot properly and would slip off mid-run no matter how I adjusted them. I had to use it over my toes instead. Not a major problem but a bit annoying considering the set-up was burton on burton. There's always risk when buying online but dogfunk is awesome and speedy with returns and all that good stuff.
