David,
I presume you mean the small bracket which bolts to the bumper behind the numberplate.
I think we may have several in the secondhand stock and suggest you contact Ian Harvey – secretary@traction-owners.co.uk
However, I know we also have at least one of the aftermarket version, comprising a support tube which screws into a special gearbox bearing cap. This offers a much more rigid support and eliminates damage to the bumper and grille.
It will require a different handle with a larger diameter shaft to suit the tube and I am sure there is one of those in stock as well.
