I have a fan and clutch assembly dated July of 69.
Is the clutch specific to certain RPO engines?

The cluch was specific to it application. For instance the clutch shaft length was different on BB vs SB, in addition RPM operating range called out different clutches. For instance a Z28 had a different clutch than a 307 with A/C due to rpm range. The same applied to solid lifter L78 vs L35 w/C60,K02.

Thanks Steve.
What clutch shaft length would be correct for a 69 big block, and what would a small block be?
