The instructions for installation are in the images on this page and the next.
NOTE:
Before beginning, we recommend that you remove the two side screws
completely at first, and
apply a drop of blue thread locker
to each one.
Although they may stay tight just fine, this extra procedure will insure that they
don’t vibrate loose over time. After applying the blue thread locker, thread the
side screws back in partially then proceed with Step 1 below.
You may want to leave the side screw just slightly loose while you line up the
two front holes with the adapter plate and rubber well nuts in the bike plastic.
However fully tighten the side screw before fully tightening the front screws
because this will help pull the front assembly inward for a better fit.
