A 60-something amp alternator will have twice the capacity of the original equipment generator, so unless you go ape on add-on electrical accessories, you really don't need anything bigger.

For power seats, windows, electric wipers, air conditioning, a high-wattage sound system and maybe a power buttwipe- - - - -upgrade the alternator accordingly!
