I agree, looks as though it is welded off center, have you measured it to see if that is the case?
Usually Bushtec is a first class item, may have been made after the sale of the company.
I too am having the same problems as lvse110se5
I've been looking at this hitch I bought from Bushtec wondering what to do. I called Jamie at Bushtec and told her the problems, then I was transfered to Andrew, and then to someone else. I'm not totaly sure, but IMO they know they have a problem, but they're blaming it on HD. Bushtec also informed me they are working on a new center piece that the Box tubing is adjustable so a person can square it up with the rear fender. But they didn't have one in stock to send me.
I took the hitch on the bench and put a square and a tape messure to it, this hitch is far from being straight. Bushtec said that's the pattern they got off the 09 bike. I was told HD must have changed things on the 2010.
With this hitch being so out of square, I can see why the Box tubing is off center of the rear fender. I don't think I'm going to put washers on one side to shim it out.
Still waiting to hear back from Bushtec on what to do from here....
