Re: Aluminess Rear Bumper Install
I hate to tell you this, but the issue with the holes probably wasn't due to your van being a 92, but the frame rails drooping outwards.
Once you remove the stock rear bumper, the rails tilt outward and the holes don't line up. (this is worse with the xl storage box which requires a crossmember be cut out)
What you do is install two of the bolts, and I cut a piece of 7/16 threaded rod long enough to fit across the frame rails, and then put nuts on it and large thick washers, and I tightened the nuts until the frame rails are parallel to each other again, and voila, the top holes line up. Torque the bumper bolts and then remove the threaded cross rod.
I think it is too much of a coincedence (I too only had 2 holes line up until I corrected the issue) to be anything else.
I have pictures somewhere if you are interested.
