Info on correct Rear Mudguard fitting...........could someone shine some light on the Crossover point when heavyweight Twins and singles for that matter went from One centre Bolt fixing for the detachable section, to ....Two Bolts at the joint..???? I have different contradicting information with this Little Gem, but I think it should be a correct Part for the correct year of Machine. Any help Really appreciated. Part No 021710.

Rear mudguard swinging arm touring models, 49-52 had a hinge joint. 53-54 had a 2 bolt fixing. 55-58 had a 1 bolt fixing. 59 on was one piece.
Cheers Dave.
