For everyone out there who has purchased an Olympic Defender rear bumper only to find that Olympic suspiciously failed to mention that you need to permanently remove your rear tow hook in order to install it, I have an easy mod that allows you to keep your tow hook in its original position along with your Defender bumper.
You will need a drill press (although you could possibly use a handheld electric drill), a set of metal-boring drill bits that go up to 1/2", a bench grinder (or other decent grinding tool), and (3) 1/2" X 2" galvanized bolts, along with matching nuts, washers, and lock washers.
You simply drill holes into the Olympic bumper mounting plate where it matches up with the tow hook side-piece. You'll probably need to start with a small bit and work your way up to the 1/2" one, since the metal plate that comes with the bumper is fairly thick. USE SAFETY GLASSES!!!
You will then need to grind one side of the washer on the rear-most frame-to-plate attachment bolt (see last photo) to accommodate the side piece of the tow hook. In other words, grind the 7 o'clock position of the washer down enough to allow the tow hook side piece to rest against the frame without it sitting on the washer.
Then simply bolt the tow hook back onto it's original location, and attach the 2" bolts right through the frame and Olympic bumper plate. Use both the standard and lock washers on the outside, and tighten the bolts up with the nuts placed on the inside. The third bolt goes up through the bottom in the existing hole (no drilling needs to be done here because the Olympic bumper plate doesn't block that hole.) You now have your tow hook back, mounted securely in its original location.
