Do you have any photos of this?My panel "Volunteered" - those silly plastic 'fasteners' came loose on their own so that the door couldn't be opened except by being inside and holding the panel so it didn't catch on the rear of the opening.
So - taking a hint from a Norwegian coin with a hole in the center - I selected a half-dozen assorted "Quarter" [US 25¢] size coins from an earlier European trip in my Vanagon, polished them, drilled center holes and fastened the panel with sheet-metal SCREWS using these coins as 'washers'.
Looks spiffy, panel is easily removed with a screwdriver, and - another extra cost, "Special Tool". eliminated
I particularly like the pre-'euro' french coin which still looks like gold after several years.
