If you are using the KOP frame we had good luck with a technique that is probably in the CD image archive somewhere... at least that is where i think we got the idea from.

Use an eyebolt. If you pick on the right size (1/4" seems to work nicely) you can just run a bolt through the KOP frame rails and eye of the eyebolt to hold it together.

To screw the eyebolt into the bumper we took a small piece of 1/4" band iron, drilled and tapped a hole for the eyebolt, along with a couple of small screw holes.

We drilled a hole in the plywood for the eyebolt to pass through, then screwed the band iron into place on the inside of the bumper.

This worked well.
