if its the equipe that is the same shape as the one-design, the gasket is hinged, it snaps open revealing a bunch of screws, like adam says, be gentle. don't pull on the black rubber, maybe wedge a screwdriver under the white plastic at the ends to get it started. if its one of the rare XR's; the gasket may simply be glued on like the later equipes.
hi Paul, i recently spotted what i thought were boxes of those gaskets at windpower windsurfing while visiting wisconson. turned out they were for a smaller mistral and a couple of inches shorter that the ones we need. did however get some parts for the track. my bunnings door seal gasket works ok but needs to be stiffer, i will try pattern-mylar next, works perfectly on my div2. Doug.
