Need help to identify fan clutch
 

I need help identifying this fan clutch. I picked this up this weekend at the local swap meet for $10.00. It has been date stamped twice 3 21 69 SC and 2 13 69 SC. It has a few chipped fins. Here are the measurements.
depth 1.375"
hub 2.125"
bolt pattern 3.250" across
Thanks

I believe the 2.125" hub and 69 date mean it's from a Corvette. Sorry I can't be more specific.
