Hi i was reversing over rough ground today and i have knocked a plastic panel off from under my van, The panel is about 10"x12" with a bit sticking up like an L shape and that bit is around 4", its held in place with like a rubber cable zip tie with a block on the end so as you pull the rubber strip it clamps onto something. I have had a good look under my van and cant work out where its come from, i tried to upload some pics on here but it wouldnt let me do it. Has anyone got any ideas please, Thank you for any help.
