I have tried to put the hardtop back on for the first time and am not sure its on properly. The passenger side rear side catch seems to be missing a washer. It is very secure annd not going anywhere, but there is a good 4mm gap around the rear sectiion. Is this the way it should be?? Tried many times to resdjust but we could not manage to seal the gap with the mechanism. Had a new soft top fitted at the start of summer and the garage said the meachanism was working well. Any help would be appreciated.
