The holes are in the right places for the hitch and bumper (almost), the problem is that the frame has a bend in it right at the shackle mounting point. It is not a problem with the car since the frame is boxed at that point and would take a serious accident to bend it. And both sides are identical.

The bottom of the stiffener is flat it's entire length. Therefore, it touches the inside bottom of the frame at each end and is away from the frame in the middle. This is all fine for mounting bumpers that mount to the sides of the frame but the hitch mounts to the bottom of the frame. If I had tighteded the hitch to the frame, it would bend the frame or the stiffener until they met or until the bolt broke.

I've cut and welded the stiffeners so that they bend at the right point to match the frame. I am doing this right now (last night, tonight, and tomorrow) and am now about to go the store to buy nuts to replace the fixed nuts on the stiffeners. The holes don't line up now and I'd rather redrill the stiffeners instead of cutting into my car.

I was very surprised at how easily I could cut the stiffeners with a hack-saw.

There is also a bent tab on the bottom of the frame that looks like it aligns the two halfs of a frame rail when the frame is manufactured. The frame rail is boxed and made of two halves welded together. I had to heat and bend the stiffener at that point to allow the stiffener to sit flush on the inside bottom of the frame rail.

They fit perfect although I hope anyone getting these to mount a hitch reads this and isn't surprised if things are quite right.
