Having purchased a lovely aluminium fabricated tow hitch cover to replace the damaged plastic original one, I have added to it things I felt it needs - one of which is a replacement Permitted Drawbar Load sticker that the old cover came with (from the factory). As it was in German I also set about translating it into English and getting some self-adhesive replicas made. they are a tad smaller than the originals, but look fine when applied to the cover.
if anyone would like one, I am happy to send one free of charge - I have six spares to give away. If there is a lot of demand, I shall get some more made up and then, from that point on, I will need to charge a small fee to cover the cost. (estimated £2 inc postage).
Cheers,
Simon
