Bob- Like I said I installed the spacer kit on mine just because the clearance was a little too close for my liking. I have an 01' 3500 with the stock bar. The installation of the spacer kit is a piece of cake. The passenger side is already drilled, just unbolt, add spacer and move. The driver side I had to drill one hole, and then use one of the existing holes to remount the bracket.
