Hmmm, after a bit of faffing about this morning i realised the right stem is slightly lower than the left one, meaning the left one can reach a little bit of a better viewing angle than the right.
BUT, there were hardly any vibes at all on the mirrors, and the one i thought might move remained in position, and that's including a couple of roads of speed bumps too, but it is only the first day, plus it's dry as well, although thinking about it our toxic dusty rain might help keep the balljoint fixed in place.
I would say now that about 3/5ths is clear mirror viewing and 2/5ths elbows, which is much better than before.
