1972 chevrolet c20 project truck high nickel 350 block

1972 Chevrolet C-10 Additional Info:

1972 Chevrolet C20 3/4 ton pickup truck, 3 on the tree, manual shift. 2 1/2 Ton rear-end. Which i am told is rare. It was a barn find, barn roof fell in, which is why the dent is in the roof. Started to restore but didn't get it done. Here is what i did get done. Rebuilt the engine which is a 010,020 high nickel content engine, which i am told is rare also. New rockers,cab corners, inner fender wells, and door bottoms. The entire outside of the truck was sandblasted, and primed. (epoxy primer) Not the inside of the bed though. New shocks, radiator, dash pad. The bad no tailgate, and has a crack in the wind shield, needs floor work. I have been driving this truck for the last five years. I took it off the road in June, 16
