The passenger will be a different story...
I knew when I got it that the YJ had a problem. I have since exascerbated it.
When we fitted the passenger side corner to the frame there was a gap of about an inch at the top. We determined that something was wrong with the frame.
My friend, Tom, and I were under the Jeep Sunday with a cumalong to attempt to pull the bumper back into place. There was a definite gap on the passenger side that is not on the driver's side. We were able to get it close but could not use it. We decided to take it to a frame shop.
$900 he said, as the frame is bent. It seems to be about an inch out of square. Then he asked, "Are you going to continue to take it off-road?" He hinted that we may not want him to do the work. He suggested the following plan.
Back the YJ up against a large tree with the driver's side rear bumper up against the tree. Lash it firmly to the tree. Using an additional tree in a good location, try using the winch to pull the frame back into place. You'll know as the corner will fit into place. Install the other corner right them when it will fit.
I don't have a good picture of the passenger side back to show you. I'll try to post one soon.
