Does anyone know the thread size/pitch for the large bolt that connects the lower end of the rear shock absorber to the banana arm?
Many thanks

I think upto 71 was M12 x 1.5 x 85
72 and after - M14 x 1.5 x 95

I sure someone will confirm this!

With later alloy arms it's a M14 x 1.5, M12 nut and bolt before that.

ref my thread (!) from the other week:

Thanks. I've just switched over to steel banana arms to ali ones. The bolt securing the lower shock absorber mount to the arm is the same one that fitted the steel one - but its too long buy about 10-15mm. Does this make sense? The ali banana arms are 76 period by the way
