Not sure about big red but ole' yellers may be worth scrap value. Or,..... a short fat balding guy may have removed the spark plugs every year, turned the motors, kept the critters out of the holes and replaced all the brake parts just before storing them. They could be drivers. There is an $18,000.00 early deuce running around here because that's what the guy paid for it. The 302 engine in the M211's have pistons that tend eat cylinder walls so .....you know, be careful. You should be able to turn the engines by hand....make sure the darn key is off.
I would have loved to see these roll off the paint line with that shiny stream of yellow just flowing down the highway. They'd make decent Civil Defense, Emergency Measures Organization, Fire Department or military gate guards if the drive-trains are gone. M211 boxes, Hoods, window frames, fenders, fuel tanks, air paks, tie rod ends, gauge assembly, steering wheels, exhaust manifolds, spark plugs, distributors, capacitors, condensers, coil, points, water-pump plug wires, the hose from the carb to the air bath, mufflers are some of the items the trucks tend to need. I wonder if that's part of the reason these trucks aren't popular.
NDT has more recollection in his pinky finger than I'll ever hope to have so if you're looking them over and have specific questions about them, you're in great company.
