Wing Bolt Drilling Guide
Now, you'll never need to settle for a poorly mounted wing again.
Harry's new procedure uses this steel guide, which measures 1 1/2" round, 3/4" thick and weighs a hefty six ounces. The guide works for 10-32, 10-24 and 1/4-20 bolts. It comes with step-by-step instructions that contain sixteen photos showing Harry's new wing mounting procedure in complete detail.
