9. Mounting the "scissors" to the lower mount is by a rod held with cotter pins. We didn't have any 1-inch washers (which we feel are essential to keep the cotter pins alive), so the cotter pins were barely bent for now. There is a "scissor support cable" that's supposed to go in between the framerails to hold the back of the scissors up, but we used wood blocks on the axlehousing instead since the brake proportioning bracket prevented putting the cable where it was supposed to be. Actually, we have yet to figure out the real purpose of that cable.
