Re: 88 Searay Sundancer 268 hinges etc
The hinges are the same on each of the storage lockers in the cabin. They are small metal with adjuster screws.....sorry, don't have them with me so I'm going from memory.
The brackets for the rear bench seat are small and plastic. There are three of them mounted on the bottom side of the seat. The aluminum post style seat supports clip into the brackets and swing 45 degrees against the bottom of the seat where the bracket clips them into position so you can slide the seat away for storage.
