To Albert's point:

The VR is underneath the alternator. 2 phillips screws come out. You pull it out and plop in a new one. There are 2 brushes. New ones are .5" long.

Look at this sites FatsLane for the VR. Very easy to spot from underneath, especially after you've seen the photo. Helps to put front of car on ramps. It takes longer to do this than to change the part.
