C2 Knock-Off Wheel Differences by Year
From their introduction in 1963 through their final year in 1967, the Kelsey-Hayes alloy wheels went through several subtle design changes as detailed below.
It is generally agreed that no production 1963 Corvettes were shipped from the factory with knock-off wheels. But, some race cars and the first few pilot cars did have the early-style, two-bar knock-off wheels installed.
In 1964, the original Kelsey-Hayes wheels had the manufacturing dates ink-stamped on the wheel’s mating surface. For 1965 and 1966, the wheels had the dates hard-stamped on the backside. Then, in 1967, almost as quickly as they appeared, the knock-offs were gone, thanks to federal regulations. The wheels still looked similar, but the rotating spinner was considered unsafe and eliminated.
