My 70 Chevy

I own a 1970 chevy k/10 4×4 long box 4 speed manual. I bought it local in Sept. 93 I’m only the second owner. Bought new local in February of 70. I  have the original owners manual. Mostly original, it has a 350 HO high rise manifold, it used to be a stock 307 CID.  Have original hub caps and the original black/orange spare 700-15. Looking to sell, not sure of true value. No rust or dents, all original body panels. Never wrecked and always garaged.
