Being this was my first attempt there are things I learned I would do slightly different,
it was a shot in the dark on the positioning, so I started grinding in the wrong area at
first. Once I started going to the 7 and 8 o'clock position it was clear this was a better
solution. My cover barely clears the tip of the button so I could have ground out a touch
more and it would have been perfect. Either way it works great and it was an easy mod
to perform. I recommend it to anyone with a 2nd Gen Performer.
As you will see in the picture with the holding ring you can see clearly the positioning
it needs to go toward. At first I was grinding toward the top in order for the larger threads
on the unit to clear, this is when I realized that the door couldn't close. At this point I started
moving toward the lower center. One point of note, depending on the position of the threads
it will allow you to get closer or further away, these threads are shown above and you can
see they standoff. By rotating you can get another 1/8" of clearance.
