Bottom of the pedal. You can see how the screws need to be short enough to accomodate the folding mechanism. The pedal needs to fold over the vertical plate on the right hand side.
Again, the small hole is original. I needed to drill the hole for the right hand screw, while the left screw sits in a hole which I only needed to enlarge. As you can see I didn't get it all straight! Oh well. These screws have not worked loose, no need for loctite. Just the powergrips bracket you see, and the pedal.
