The saddles were then installed. We made sure the locating-pin hole in each one went toward the front, per the instructions. The U-bolts were slid down over the axle into the spring plate, and the Nylok nuts were installed. We tightened the nuts slowly, alternating from one to another to ensure they were evenly tightened. The rearend should sit in the saddle but not touch the bottom. If the gap is greater than 1/8 inch, trim the saddle taps to get the proper fit.
