I may have had some success with silicon spray. There are plastic fascia panels all over/across the (is it) the bulkhead- where the rear window hits the deck when the hardtop is in the closed position. I sprayed (and prayed) the silicone into the overlap of the plastic panels and the rubber gasket that the truck lid towards the rear window meet and there may be some relief but (s0me) squeaking still present. Inside of the car stunk from the smell. I may slip cardboard in between the overlap of these plastic panels and see if this works. I can't see any adjustment for any of the latches, yet. Thanks for cards and letters on the subject!
