One thing that I don't think has been made clear yet, and took me years to realise, is that there are
TWO bushes available, called 'pivot spacers' by Andover Norton:
this one fits the original side stand, and
this one fits later, replacement side stands, going back at least 16 years, which are visibly different to the originals and look
like this – notice how much more angular the later side stand is. The pivot spacer for the original side stand is too big for the hole in the later side stand, and the pivot spacer for the later side stand is, obviously, too small for the hole in the original side stand. That's what I found, anyway, and it would explain why AN offer two different pivot spacers. I just wish they could have made these items as original, and not mucked about with them. Anyway ... As L.A.B. indicated, when tightened the correct, tensile bolt, with the washer against its head, and the nut lock the pivot spacer in place, and the side stand pivots around what is effectively a fixed extension of the frame. HTH. I found this out the hard way, after an insurance repair by someone who had obviously got the wrong spacer and just hammered it in ...!
