Surely they are just squares of rubber with a peel off backing? You can buy them from a hardware store, B&Q etc, to stick onto furniture legs to prevent scratching the floor.Item 12 is available from Motorworks. Is 13 not available from them also?
Have you tried main dealer?Guys guys, I have one so I know what they are! Won’t anyone answer the question?
Motorworks don’t list them.
