I used a late model truck alternator. Very little bracket mods required. Voltage regulator connects with the same 2 wires. Add a 2nd output lead (8 gauge) from the alternator output stud to the starter relay stud or battery. Do not remove the OE alterntor wiring as it feeds the dash. With the new circut in tandem very little current will feed thgru the old cicut. This modification will cause the factory amp meter to be inop. It can be converted to a voltmeter or you can use an aftermarket voltmeter.
