no need to reverse ground. An alternator is not needed unless you are going to do a lot of night driving or load up your A with modern electrical assessories. You can have problems with the fan belt being to tight and ruining your water pump bearing. You also are more prone to fan belt squealing. A good stock electrical system works very well unless you overload it with electrical stuff. Most important with a stock system is good grounds! Much written on that subject.
