Thank you Jake . That's partially correct. The hubcap you posted is the same in design , yes. For 1960 AND 1961 GMCs , GMC grouped both years together as the "N" series . Both 1960 and 1961 received the same version hubcap with a paint change of a blue a center and blue outer ring accent. This is spelled out in the GMC parts books , dealer literature and data books. GMC did many things different than Chevrolet even though they are subtle differences , they make it a little tough sometimes.
