After the third time the taps broke, and used zip ties and duct tape I finally came to a solution I can live with. I drilled two holes and bolted it together. It stopped the annoying rattle when zipped tied.

Now I drown every plastic piece with Aerospace303 before I reinstall it. The third brake light for the 126 is still available, you can also just order the cover. They list it as a maintenance item...

Regarding the plastics in the Volvo’s, my 780 at 200k literally started to disintegrate without even touching it. I gave mine to friend, could not keep up with it anymore.
