Once again I needed to root around my workshop looking for a solution to replacing an impossible-to-find part for my S3. This time it was that access cover to the third brake light bulb located on the underside of the camtail. The PO used black duct tape, which although effective, looked terrible. The solution was quite easy - a piece of 3/32 clear plexiglass, sanded to accept paint, and a dab of superglue. Works great, and maybe the only solution as these replacement plates seem to be rare.
