Howdy. Just wanted to have a ramble about these. Our one (in a 1985 33 wagon) is really tatty and the material disintegrates when you touch it. Has anyone replaced one and what with? I have a spare one from a car I'm wrecking that is much better but it has a rust stain at the back and is still very fragile. Maybe it could be covered with another light material glued to it? Anyone tried this? Cheers.
