Anyway, the tiny SPA style mirrors were a pain to get tightened, never stayed properly aligned and I could see hardly anything out of them.
So, on return to the garage, I swapped them out for these! They are bigger, more solid and I have had them hanging around the garage for nearly 14 years. They fitted great and were much easier to tighten once lined up. They are fake CF but hey, if it makes me safer, I don't care!
