I have a 67 GT500. Recently the clutch fan started wearing out, so I pulled it. When I did I noticed it has C7SE-A stamped on the side of the base. The blades are C6OE-F. I have been told this is not the correct clutch. Anyone know for sure? I bought my GT500 in 1987 so it was 20 years old and obviously had some maintenance done, but appears mostly original. Also, what is the correct color for the blades? It currently has a blue center with black blades which I doubt is correct.
