Yes sir, it's about a $15 piece, not that complicated to split the case and install, but you have to do the same things as if you replace the brushes.
Take the bolts from the case halves, carefully pull it apart, disconnect the 3 solid copper wires from the stator to the rectifier bridge, take out the screws holding the regulator and brush housing, remove the diode trio, and replace the regulator, push the brushes back into the holder, take a soft item like a toothpick, or aerosol can squirt tube to hold the brushes while you put it back together, you know, reverse procedure of disassembly. Once you have the case back together, pull the tube holding the brushes and you are ready to rock, one wire style.
It takes about 1700 alternator RPM's to kick in, and every once in a while I have had to jumper and energize the regulator sense wire terminal to get the deal charging, but that is a one-time deal.
