I upgraded to Classic Retrofit. I have a voltmeter in my car and would watch the volts drop whenever the a/c compressor cycled on (Griffith's 4 condenser system w/electric fans on three of the condensers). This combined with headlights, upgraded stereo amplifier, etc drove me to the high capacity alternator. Very happy with it.
