Hello everyone,
I've had to abandon the idea of shortening the mounting thread to allow the fitment of a ring spanner. It won't work on the right-hand strut as, due to only 18.5mm clearance below the spring, there would be nothing left for the Nylok nut to attach to. So I've abandoned that idea.
Alan's earlier suggestion seems to be the only solution; a crow's foot spanner and
this one from Laser Tools looks promising particularly as it enables the use of a torque wrench.
Alan also came up with the safe solution for the exceptionally slim 5mm holding flats on the ball pin; a 16mm bicycle cone spanner. I'm going for
this one which, at 2.5mm thick, will be just right.
Thank you Alan (
clf).
I might be back later in the week if another problem crops up.
Simon
