They bolt right up but i think you need to trim the dust sheild and possibliy run wheel spacers. im doing the IFS hub conversion on mine to widen it 3 inches to match the IFS rear. you dont have to run spacers but its a lot of work.

my bumper is a ARB winch bumper, i got it and a non winch ARB bumper for $400  because i got it on discount from this guy i do business with with, they sent me the wrong one (the non winch one) and then they sent me the right one and i just got to keep the other one and he wrote it off. I bent the out of the mounting brackets pulling my buddys Bronco II out of the mud. im not to happy with it, but i made my own brakets and now it does alright
