Hi all, especially the rivet counters amongst you,

A picky electrical equipment query: what's the correct way to mount the regulator box to the rear mudguard?

I believe the bolts are 1 1/32", pushed through from inside the mudguard, but I'm unclear what goes on the other side? Post-war models -according to my deeply unreliable Haynes manual- had a rubber grommet, (regulator box), washer and nut. However, an original WM20 mudguard I have has a more complicated arrangement of washer, nut, grommet, (regulator box), washer, nut...

I'm almost ashamed to be asking such a question, but it's also comforting to have the opportunity :upside_down_face:
