I took it to a welding shop to have a custom hitch made. They first fabricated the hitch, then bolted it to the existing frame that is used for the bolt on hitches. Then they welded that hitch mount to the frame and then welded the hitch to that frame. The bolts were only used to hold the hitch in place while they welded everything else to everything else.
