Hi folks, apologies if this question has been asked before, as I’m new to this forum. Does anyone have the official part number for the rear threshold cover on a Vivaro B (LWB 2014 -2019 model). It is not the part that covers the rear bumper but the part that covers the inner threshold. I have kept the old van one, but I’ve since laid 12mm plywood covered with Altro flooring, and the old van one no longer covers. I believe one made for a mini-bus or combi might be best? TIA, I appreciate your help.
