it,s not a difficult job on a ramp, but could be a bit awkward on the floor, the drivers side wheel will require removing and the wheel arch liner, this will give access to the bottle and piping, if you require step by step instructions please let me know,
no problem at all, always interested in reviews so please report on how you et on as not all people are willing to travel to Derby and currently only recommend a few dealers, depending on where the owners are, at the moment i only recommend HWM in your part of the world,
