The rear support plates cover the ABS holes completely. Was yours a Sport bar? If so, then this is very peculiar. I mean seriously, I even used part of the ABS line hole for one of the rear support bolts. All I had to do was drill it out a little.
I had to disconnect the ABS harness and pull the wire out of the hole before I even set the bar in the car. It would completely have crushed the wire.
