About the grizzley tool... 
In case anyone is wondering how the tool works.
The sights are the plastic cylinders
with precise cross-hairs at the bottom.  The cylinder 
gathers a surprising amount of light on the top portion 
(the part that sticks out of the black aluminum holder) 
and effectively illuminates the cross-hairs and what 
you want to mark.  When everything is lined up, you 
hold the holder in place, then pull out the plastic 
cyclinder and replace it with the metal center punch 
and give it just a "tap" with a small hammer.  That will mark
the exact spot where you want to drill, punch or whatever.
There's a piece of rubber on the bottom of the aluminum 
holder to keep it from slipping while you're doing the marking.

Thanks Charlie,

That looks the part for the lens (The hard part).

Just need to replace the marking punch with a
hole punch and probably a through bore on the
holder. Or maybe a complete replacement holder &
punch.
