Just purchased a 1977 Chevy fleetside in almost showroom condition. Truck only has 79,000 original miles and is close to rust,dent,and ding free. Original build sheet says it was C20 fleetside camper special with E81 wood floor, GT4 3.73 rear , both kinda unusual. Engine and tranny have been swapped so numbers matching out the window, but still is really clean and original every where else. Still has most of the paint on box floor, doesn't look like box was ever used. Old,really old dealers I know say they never saw a fleetside pickup with a wood floor,let alone sold one.
