This is the first time I have attempted them. The instructions were not very helpful since they just showed them as one whole assembly that you just slide right on the vehicle. Don't think it works that easy. Kind of a learn as I go type thing, seem to do those alot.
As far as the paint and the tracks, I did it like that to confuse the mind of a young gun, and it worked!
Actually it's just how they wound up in it. That and had to take a break from the tracks between sides, so I painted some, since there is plenty of that to do as well.
