i have a small raised area just above the window on the passenger side, so I expect it would be difficult to peel back the material to view this. I see there is a company called carhoodsdirect.co.uk that supply a roof kit. The car they show is a cabriolet but I cannot understand why it fits models only from 1987. It is one of those jobs that once you start looking at can become a hard to sort out. This could have been there all the time I have owned the car but now only found by Laurence advise to check this.
