Sliding hatch for V20 cuddy cabin

I am in the same boat ;) (V20) for sure) with an 84 missing the first slide (nearest the door) thanks to Hurricane Charley (Posted May 26,05). I contacted Wellcraft with the same results. Is anyone aware of what years will interchange? I am thinking of going the remanufacture route if I can "borrow" one to use for a pattern.
