I have a 1967 plus 4 originally exported to the USA. I have oblong black and silver die pressed alluminium plates front and rear. The rear one is filled on the valance behind and below the rear bumper and has bottomed several times skurfing the bottom edge of the plate. I am contemplating changing the rear plate to an oval one and attatching it to a self designed mounting plate that I can fix using the spare wheel securing bolt. This way it will be out of harms way, be more visable and will lend itself to incorperating a third high level stop/rear light. PS I know it will be bit of a phaf when removing the spare wheel but think perhaps the advantages will outweigh the disadvantages. Thoughts?
