Jack's Comments:

Concours Notes:
1) If your Hipo 289 was built later in 1966 production this zinc dichromate plated pulley is correct for your car.
2) To help you determine what pulley/fan finish is correct for your 1966 production car we have documented several confirmed survivor cars below:

Documented Original Mustangs from Bob Perkins Collection:
Black Fan, Black pulley March 9,1966 289 4V Dearborn built 6,000 miles
Black Fan, Yellow zinc pulley April 1,1966 Hipo 289 Dearborn built low mile survivor
Black Fan, Yellow zinc pulley June 6, 1966 289 2V Dearborn built 54 miles

Other documented original fans and pulleys:
Blue Fan, Black pulley November 12,1965 6-cylinder Dearborn 33,000 mile
Black Fan, Black pulley Feb 19, 1966 289 Hipo San Jose very low mile survivor

3) The only reason this pulley is not rated a 10 for accuracy is because the originals were machined with crude early versions of CNC equipment. These crude machines produced pulleys with uneven surfaces and random swirls left on the face of the pulley as the cutting edge was pulled away. The new CNC manufactured reproductions are so perfect compared to the originals they can be pretty easy to spot.
