Give your AMC the charging power that won't dim your lights, lose battery charging while idling at stop lights, and the extra power you need to run a modern stereo system, digital A/C, electronic gauges, and other electronic accessories. Our alternator is proven and fits just like your original Motorola case did (provided you are running factory accessory brackets, aftermarket accessory brackets may require modification to fit). You'll be able to get rid of the 3-wire hookup which will clean up your fenderwell too.
