Want to add new Carolina Skiff accessories to older hull.

:?: I have a Carolina Skiff J-14 skiff (1994 hull), I have recently wanted to update its useability. I am wanting to add a rear deck with livewells (accessory). I have one of their brochures which give a width dimension of 55", however my hulls width dimensions are 56-1/2" (there is an overhang on the decks that rest atop the gunnels. I was told by a dealer that it would not fit, he only wanted to talk to me about buying a new hull. Has anyone that you are aware of added a newer rear deck to an older hull?

Thanks for any help or suggestions. Snookhunter
