Rating: (see review/s)

"The alternator was the right one with the exception that it didnt truly fit the engine properly....the back bolt position was wrong and thus had to be modified to fit. Given ALL the specs required this should NOT HAPPEN; and given I bought the more expensive OEM part that should have been EXACT...BUT WASNT. cLOSE IS not good enough WHEN DEALING WITH VITAL ENGINE PARTS so more care and attention is really in order here...." posted by: videojoe on June 17, 2013
