Gill if you get stuck try cosoli they do a neat one, Doddle to fit only 4 bolts under pipe,And you will need to relocate the number plate light,You get all the right bits in the kit.
i bought the Casoli item-its an Evoluzione one. I altered the mounting bracket so the plate hung lower, and you can mess about with the std n/plate lights with the kit provided to make a neater job.
