Hello to all I have a question about the upper control arm mounting points,has anyone used the upper frame holes. What angle is best to use. My trailing arms are mounted on the lower holes and I was wondering does the ride change much with the increased pinion angle with the arms mounted on the upper holes. I am also thinking about getting new upper and lower urethane bushed control arms and using the stock rubber type of bushing on the diff unless some one has any other input.
