Fan Clutch Delco Aire Information
 

I have had an NOS Delco-Aire part number 15-443 fan clutch in the box for years. It looks just like the small Eaton version used in the 60's. I am unable to identify it. The bolt pattern fits Chevy fans, but the hole for the hub is a bit smaller. Profile actually looks like a BB 67 style Corvette.
Any assistance would be appreciated.
