I don't know of one of those available but I do know an excellent source that may be able to help you. There's a dealer in the small town of Pinckneyville, Illinois that was one of the first Benelli dealers. They still sell a ton of Benelli guns and parts.
Mann & Son (Since 1945) is a full line dealer for several makes, including the Benelli line of shotguns. They're also an authroized Remington repair station. John Mann is the best gunsmith that I've met and is a very helpful guy. You can reach them at 618.357.2911.
Hope that helps.
