I'm using NC29 mirrors (as NC30 mirrors arent available) and went to put them on today using the same nuts as before but it doesn't seem to thread properly. The thread looks the same to me if only slightly different, what nut should be used? I'm using M6

thi is one part that i will not buy a replica for. Every single one has been crap, cant see shit out of them as they vibrate just on idle, last set broke the "mirror" with a light tap on the garden gate.
This one i will fork out Honda prices for as they are solid, last 50 times longer & take harder knocks.

Mine seem alright so far, just a bit tight about a third of the way down the thread. Angle isn't brill but ok when not full packed.
