Several could have been used. GM #343720 or GM #460742. If the car has C-60, then it's likely GM #343721. However, I don't think you find any of these numbers on the clutch.
The 343720 and 460762 are discontinued and replaced by GM #88961763 which is also now discontinued.
The 343721 is discontinued and replaced by GM #88961768. The latter is the fan clutch that I recommend for your application whether or not you have C-60. If replacing the 343721 it will appear virtually identical. If replacing one of the non-AC clutches, it will appear considerably different. However, the 88961768 is the best performing fan clutch EVER installed on a Corvette. Period. However, it can be a bit noisy but it cools.
I still suggest that you post a photo of what you currently have.In Appreciation of John Hinckley
