Thanks very much for the offer, but it's quite a bit different. While the Pinky one goes through the floor and attaches to the chassis outrigger, the Series 3 one fits to a strengthening plate which lies on top of the floorplate and footwell and is fastened in by the standard floor bolts. I suppose they made them like that so that they could be swapped from vehicle to vehicle without leaving too much damage. Thanks again, I'll find some pictures eventually.
