You will want to start by flipping
the mount upside down and mark where your hole will go. Make sure it is even
on both sides before you drill. There's nothing more aggravating then to have
your mounts off balance from one another.

It's now time to take that deep
breath and drill a big hole in your ride! Don't worry it gets alot easier after
the first one. Once both holes have been drilled out you will want to try and
push the mount in.
The 3/8 saw is a bit smaller
then the actual mount size. You want to make it as snug as possible. Take the
file or dremel tool and begin to fit your mount. It should be tight enough
where you will need to take your fist and give them a few taps to seat it.


After your dry run is complete
and the proper fit is acquired then take your silicone and put a healthy dose
on the underside of the mount. After they are seated for the final time and
all lined up in the position you want, you can begin to install the fasteners
of your choice.

Easy as pie! In my
opinion the yak looks much cleaner with these installed.

It's great to be a DIY-er. You get the satisfaction of doing your own
customizing and coming up with your own ideas. Good luck with this project.
