GMC lists 2 different hoods for 1953. One for 100 through 250 and another for 280 through 470. Fenders came in 3 different sizes. 100 through 250, 280 through 350 and 400 through 470. There aren't near as many 400 survivors as 300 series survivors. The larger hood shouldn't be that hard to find. Shipping can be a problem. They do come apart in the middle and Greyhound will take them.
