You are right about this but unfortunately no one asked me whether I had a D4D before selling me a Towsure bracket for my tourer. I fitted it today; I had to 'trim' one of the brackets slightly to ensure that the exhaust tail pipe didn't knock against it. I know this sounds a bit dodgy, and I shouldn't be messing with a type approved piece of kit, but there is still plenty of meat left on the bracket; it is made out of 10mm thick steel. Stephen
