I've got a RB6 in 3 Gear stand up setup. I've lost the small little black circle cap that covers the top shaft bearing on the side opposite the slipper and spur gear side.

Rather than spending $10 for the whole 3 gear kit and getting all the extra parts again, any solutions as to how to close that up? It appears its just a cap to keep dust dirt from reaching the exposed bearing and top shaft end. I believe it's 10mm wide so not sure if that helps locate any replacement options.

Thanks in advance.
