Has anyone fitted one of these, like RR UK's version?

 I know it's not a big deal, but with the stock hydraulic unit known to fail and also cause a lot of un necessary wear on the motor until the oil pressure builds, it probably good if someone who has done it provides a walk through of the process for others to reference.

Hey bud, don't sweat the rod knock noise. With a flat aluminum skid plate they all sound like that. Try a piece of dense foam between the skid & motor then drill a small pattern of holes in the bottom of the skid to take the "ring" out. It works best to put a loud pipe on then you don't hear the mechanical motor noise.
