Is the fan loose or from a Camaro?

For 1968 Camaros with hydraulic lifter engines with AC or K02 (except 1968 L34/L35 with K02), the 3789562 fan or the 3931002 fan was installed. (The 3931002 is a seven blade fan with limited observed usage.)

Thanks Kurt anything on the clutch?

Nope. I don't recognize that #.
