I attached the little black box on the back of my remote for the extra crystal.
And believe it or not, The crystals fit like they were made for the box.
I did sand the edges of the crystal, So they would slide in/out very easy.
You can see inside where the original crystal would have fit and I cut the stem off of one crystal
to mount the wiring too.
All I need now is my 0n/off/on switch.
Once I get this complete, I'm going to give the whole remote a new paint job to match R2's colors.
