Historical Details

Fan & Pulley History: 1965 alternators before 4/65 have a different pulley fan & spacer than later units. The early style fan has a flat center (not dished), the pulley has a longer hub and the fan spacer is thicker. When assembled there is is an 1/8" gap between the backside of the pulley and the fan. The later fan & pulley replaces the early style nicely. All 1965-66 fan & pulleys are painted semi-gloss black, the fan was dipped in paint and the pulley was spray painted. For a period between early 1967 thru 1969 the pulley was plated zinc dichromate (gold color) instead of painted. About 1970 most common pulleys were again painted, semi-flat black this time, single pulleys entirely and double groove pulleys had the front only painted (over a zinc dichromate finish). All 1967 and up fans are zinc dichromate plated. Beginning about Nov. 1969 the fan changed from a 13 blade to a 10 blade style. Other Changes: The nut & washer used  to retain the pulley was silver zinc in 1965-66 and zinc dichromate 1967 and up. The thru housing bolts were zinc in 1965-66 and zinc dichromate 1967 and up. All 1965-69 alternators have 10-32 terminal threads and 1970 and up units have 10-24 threads. The FLD terminal insulator is white with square side 1965-67, beveled sides 1968, orange with beveled sides 1969-73. The 1965-67 STA insulator is black with square sides while the 1968-73 insulator has beveled sides. The BAT terminal insulator has beveled sides on all 1965 and up units. There were minor changes to the rear casting as shown below.

When ordering carefully choose type 1 or 2 indicated at the end of the part #, ex: C6AF 10300-F1. 
All AMK type 2 units look like type 2a. 1969 vehicles built after Feb. 1969 have a die stamped ID # instead of an ink stamping. To order the die stamped unit choose a part # that ends in "D",
 example: C9ZF 10300-B2D. All 1970-73 units are die stamped.  Fan & Pulley are sold separately.
