You might need to turn the right peg 90 degrees so the bolt runs front to back. when you take the peg off, there is an allen bolt holding the cap on. We had that apart when removing the controls from Justin’s bike. Also, you can shove a washer in there and it will be fine. HD’s aren’t spring loaded like the buells. They have these spring/washers that don’t work very well.

Definitely like the setup. Wheels, bars, pipes…
