fan spacer

Can somebody help me out with the correct length fan spacer for a 67 gta 390/w ac and stock radiator?

This application did not use a spacer. It used a fan clutch assembly. The Ford part number is C7OZ-8A616-C and it was stamped C7ZE-B. It was also available under Motorcraft part number YB-107.
