@bluefish its always something isn't it! It looks like per post# 58, you solved your issue. When you get a chance post some pics. For what its worth here is my setup. I can't remember exactly what holes I used, as the PO already had a makeshift ball hitch mounted on my frame. I reused two holes, and had to drill two additional holes.
I do have a gap between the bumper and the hitch plate where the two holes mount into the frame. At some point I should put a metal plate in there.
