I have a bezel... colors might be a little faded, and there is a little bit of work to be done at the bottom of the bezel (a few scratches, and paint starting to come up an a few spots).
However, I do not know how to safely ship a glass bezel.
I may have a trackball controller, but it will need new shafts, bearings, and it should have a new ball.... so probably better to find one you can use.
You can PM me if you can't find anything else and want more info.
