That's probably easiest. I just do it with the box all together because with the 8ight, you have to get the wheel perfectly in the slot... So I put the pegs where I think they'll fit, make them tight enough so they won't move on their own, but you can move them by hand. Then I put my buggy on the box and slide the pegs to where they actually need to be, then tighten them up, and walla.
