I don't have a tip for the soft top seal, but I do for the chrome trim on it. There are small nuts & bolts that hold the pieces of chrome trim to the soft top lid. These all have small rubber washers with them. This prevents water on the soft top lid from flowing below the chrome and into the lid itself or into the soft top compartment. These nuts, bolts, and washers have individual part numbers and are still available.
I belive the chrome strips also have rubber seals that run along their length.
