Just thinking. I would probably only wish to fit 2 badges. Perhaps that would be possible by just making 2 small plates, one to fit over each protruding stud, and with the two bolts for each badge hidden below the top edge of the number plate plinth. These could be made of aluminium as its corrosion resistant and easy to work compared to S/S (and I have some). The 2 plates would be held captive by tightening the nuts securing the number plate plinth. Or I could even use one smaller plate made of aluminium, to fit over the studs as above - then no chance of rotation.
