i agree with some, just use a hammer, sledge...provided you have on, to bang the ends od the frame rails a bit, mine was off as well, and had to do some tinkering to fit it on. but i also pushed the rails on the arb apart with a hi-lift jack, and a ratchet winch, haha, but some hammering should do the trick, and the bolt holes will line up, even though it is off set a little.
