I have a NOS clutch fan with a part # 3946050 CZ stamped on it. This is the one listed in the assembly manual for the L78 option.

Camaro L78's and L72's used the CZ clutch.
CV was Z28.

I didn't know that.That's different from the Chevelle application.
That's also the same part# & prefix for the 1970 L-78 Camaro too.

Hey guys thanks for the information, I also researched my assembly manual and my parts book and came up with the 3946050, but neither stated the letter code. Any one know what the JA application is for?
