I thought that these stainless steel door “threshes” – from a company called YRM –  would be a decent addition to my Defender. As can be seen in the first image I previously had a mixture of unpainted metal, floor mat and seat box covering in that area. So, removal of the existing bolts (rusted as expected), an underlay of duct tape (pretty useful stuff in a Land Rover this vintage!) and installation of the strips was easy enough for us to accomplish. Looks a lot neater now.
