To prevent that the heat from the outlet will heat up the floor, heat shields are provided on the underside. The heat shields are made from asbestos and are covered by a thin layer of aluminium to prevent the asbestos from crumbling. These aluminium asbestos protection plates where corroded and need to be replaced by new ones. The asbestos shields are still in good usable condition and will be reused.

Because the rivets, used to mount the asbestos and aluminium sheets to the steel floor, can only be used one-time I started to search for them on the internet. After some time I discovered a bunch of brand new, by Jaguar so called, “Bifurcated Rivets”
