I have just fitted the Bearmach 'Safari' cheaper lookalike, because i don't like the mushroom type, to my 200Tdi,it comes with all the instructions and fiittings, you need to drill 8 holes but they tell you where and what size. A good splodge of silicone around the foam gasket they supplied, screw it on and thats it ! 1/2 hour tops !, Got it from E-bay at 95 quid plus vat & post.
