Discussing the external rear view mirror arms (with the spring loaded rotational mount at the door hinge end and the ball at the mirror end).
I need to remove mine (removing to repaint after corrosion removal) but the hex socket (underneath the plastic insert) has a measurement of 7.7mm between flats
Looking at an fractional imperial to metric chart I see that this measurement sits between:
5/16 @ 7.94mm (too large) and 19/64 @ 7.54mm
I don't have a 7mm hex key, but suggest it would be too small anyway, so is 19/64 a common hex key size ? And why would LR do that ?
Removing the whole lot (door hinge etc.) and masking the joint for painting it is an option, but I'd rather just go direct if possible.
What am I missing?
