TWO CORRECTIONS TO THE COMMON SPEC BLOCK:
• Many listings say the regulator is EXTERNAL, it is INTERNAL
• Many listings leave the groove count blank or say internal
• Delco, ARCO and the rebuilders all list SIX serpentine grooves
• An external regulator unit wires differently and will not do

HOW TO VERIFY FIT:
• Count the pulley grooves, this unit has SIX
• The pulley is solid serpentine, 2.193 in / 55.7 mm across
• Count the mounting ears, this unit has THREE
• Ear 1 is M8-1.25 threaded, ears 2 and 3 are 8.4 mm plain
• The B+ stud is M6-1.0 with spade S and L terminals

DO NOT ORDER IF:
• Your old unit uses an EXTERNAL regulator
• Your pulley has ONE or TWO V grooves instead of six
• Your pulley measures 2.44 in, that is the 19020609 unit
• Your old unit has only TWO mounting ears
• Your engine is 24 volt, this unit is 12 volt
