CRG info...

Fan for L78 and Z28 and 1968 L34/L35 with K02
The 3871276 fan was used on the 1967 and 1968 Z28 and L78, as well as 1968 L34/L35 with K02. The bolt circle diameter for the clutch-to-fan attachment was 3.25-inch. It thus required a different clutch unit than the fan clutches used with the AC or K02 hydraulic lifter engines.

My 68 Z28 uses a 4 rivet fan and the smaller hub.
I have an NOS 4 rivet fan and matching clutch. Posted here a few weeks ago to determine application.
