I really love those brackets. I had to cut 2 small pieces of the ARB deluxe bar mount on each side in order for the shackles to fit. I was really stuck in mud once and my friend who came to get me out got stuck too. It took two tow trucks to winch me out of that mess. The factory hook would have been bent or broken off for sure.
If there is another run for those, I'm in for a pair + bolts etc.
I had to cut the bumper too but never got around to it so I put the stock hooks back on. I just got the FRBs refinished last month so maybe I'll get around to it sometime soon.
