Fan Clutches

[copo69]

Can someone educate me on the differences in 1969 fan clutches. Is there a difference in spindle length or other physical differences? I need one for a 69 L72 in a big car and see original looking ones for Chevelles and Camaros but nothing for big cars other than generic one size fits all.

Not sure if this answers your specific question on the correct clutch for an L72, but this is an excellent thread with lots of detailed pictures:
