I suspected that is what you were basing the advice on. I am not having a go at you. It wouldnt be the first time part number was noted as fitting both vehicles but was wrong. When the ladder came of my D1 and sat on my D2 door the bottom mount was in the middle of the plastic box that holds the handle for the door and numberplate light. I am giving you my experience from actually doing it not from a part number.
Cheers
