What do the hood and grill look like? How many headlights does it have? If the hood has the "eyebrows" on it and dual headlights, then I would say that you have a 1961. If the hood is the same as the 63-66 trucks and you have single headlights, then the truck is most likely a 1962. Look in the gallery at the differences between the two model years and this might clue you in to what year you have.
