My boat is a 2001 Pilot 34 Hard Top. The shroud is held in place with screws which are easily accessible. The joint is caulked to keep things water tight. Since the upper track must be loosened to slide the door out, the shroud/cover needs to come off. Take a look at the diagram of the upper track on Boat Outfitters site and you’ll see the wheels are held captive by the track. I replaced my upper track since it was split. Make sure all screws on the track are flush so as not to interfere with rollers. Hint.. don’t re use the stainless screws if the heads are even slightly damaged. Buy some new screws and match the Phillips head driver accordingly. (Ask me how I know😎
Good luck with it ... a rewarding repair!
