The most unique feature of the 1960-1961 Chevy / GMC Truck is the design of their hood. It is not in any way similar to the year before. Whether you like it or not, there is no other vehicle with an appearance like this Chevy and GMC Truck. As GM was known for saving on tooling costs (especially with trucks) this is a perfect example. The large sheet metal hood is the same on GMC and Chevrolet trucks but the parking light housings are different!
Look at the attached photos. You will see how GM gave each of their two brands a different look while keeping the same hood.
