Well, last weekend I was leading a trail ride and got into a mudhole deeper than expected......anyway, the alternator stopped working shortly afterwards and is now toast. What do you guys recommend as a replacement? Autozone and Napa both list one around 78 amps, and one around 105 amps, but the Autozone guy told me the 105 amp wasn't a direct bolt-in??? Does anyone know what the factory alt. was rated at ('90 Silverado model). I'm hoping to have my winch mounted later this spring so something around 100 amps would be nice to have.
