I have a '76. I purchased this drop bracket, installed as instructed. Also purchased the chromoly track bar. The track bar comes with bushings that use a 9/16 bolt on the frame (drop bracket) end, but the drop bracket has a bolt hole for the track bar that is 5/8. Obviously we don't want a 9/16 bolt that will allow play within the 5/8 bolt hole in the drop bracket...how to solve?
