Camper Shells for 1977 Bonanza w/8 Foot Bed?

[LBJ]

Does anyone know of current manufacturers of camper shells for older P.U.'s with 8 foot beds? I called one company in my area and they show nothing out there. He said they may have destroyed the molds. I once had a brand new camper shell but that was in 1978 or so. LONG time ago! Gave it away 10 years later after I no longer had a place to store it (apartment living). Need one to haul a large RC biplane in my old square body. I can use a bungee cord cargo net, and right now that's about the only option I can find. Thanks. LBJ
