Main leaf cracked in a very similar position to Vees
Use a thin, flat cutting disc, not the thicker grinding disc with the offset mounting flange, these came from Halfords.
Main leaf cut through as close as possible to the eye, then a thin cutting disc up the sides of the eye cuts through the bolt and ends of the spacer tube, just clear of the sides of the bracket. The little ring is what is left of the end of the spacer tube at the bolt head end.
The thread side of the eye, with a flap of the rubber bush and end of the spacer tube that side left attached, the tube only seizing along the plain shank part of the bolt, which is a snug fit in the tube, and not the slightly narrower thread which extends into the tube that end.
