The studs are installed in a v-shaped pattern down the center belt and each one is a quarter-inch farther inside the track than the next. The pattern repeats every six studs. Once I started measuring I realized that each little “scale” in the Cobra track equaled a quarter inch, so it made it easy for me. I just double-checked the placement each time to make sure I wasn’t in the wrong spot and went for it, placing each stud a scale’s width inside of the last one.
