I inherited a 1962 F100 Unibody, short box from my uncle. It has a 223 engine, 3 speed manual shift on the column and is all original with 137,000 miles on it. Says Custom Cab on the door. What can anyone tell me about these pickups? Were there very many unibodies made? It is in great shape with only the red paint fading. (Color is red/white) He had kept it in his garage and only took it out occasionally. It even had old cracked fabric tires on it ( date of manufacture on tires was 1973!)It runs great, looks great. Any info would be appreciated. Are these things worth $$?
