What's it Worth? - 1967 C10 CST

[Mt Man Chad]

Looking for input from others what you think the value of this very early 1967 built in October/November of 1966. Original speed warning dash still installed, the 327 engine has been replaced with 72 350 4 bolt main from another C10 4 core radiator. Bed wood is pretty trashed but can support a load. Original buddy bucket seats few small spots of rust on rocker arms and back of lower fenders. Runs super smooth original turbo 400 trans and 12 bolt diff out back. New dual exhaust and BFG radial TA tires. Just curious what people think it's worth.
