I painted and installed a stage 2 front bumper last weekend. No problems at all with fit, just leave the bolts loose until they are all started. I did have to "wedge" the front up before tightening the bolts. Bumper angled down slightly when it was lose and I wanted the receiver to be level.
Tried to re-tighten bolts on Wed and all were still nice and snug. It was just what I was looking for in a front bumper: recovery points, a 2" receiver and slim/small overall look. With any luck I'll never need to know how strong it really is!
EDIT: I did not have to trim anything to fit, just swung the fender brackets out of the way. I am going to trim the front fenders level with the grill, it looks odd with that part hanging down. I also attached the vacuum tank to the pass side bracket, there was a perfect hole already there. Swing it back up, tighten the bolt and you can barely see it.
