Pulled the boot lid lining and tank cover, with a view to replace them with ABS sheet - hate the worn, frayed appearance, damaged screw holes etc of the card stuff. Plan to locate the tank cover differently - probably modern plastic stud type things, with the mounting metal reshaped a bit. Disappointed to find the brace for the spare wheel carrier is a bit rusty - applied some Killrust . I can get ABS in 2 and 3mm sheets, and in a 1220x1220mm (Close to 4ft) sheet, from which I can get the lid liner, and the tank cover. Plan to leave wider edges on the sides, so the screw holes are further from the edge, reducing the likeyhood of them breaking out to an edge. I have an old boot lid stored under the house, so I can do all the fitting tests on that . Might add a strip of alloy along the front edge to stop it bubbling between screws.
