Take a look at this post of mine from a few weeks ago this should explain how to do it pretty good. I don't think I left anything out but if I did I'm sure someone can add to it... Dave..

Alternator clocking is viewed from the rear to determine the correct position for the location of the plug. Early alts have 4 positions, 12, 3, 6, and 9 and late model 1986 and later has 3 positions, 11, 3, and 7. Using the adjusting tension bolt hole on the front case as 12 if the plug is directly behind this bolt hole. A fairly simple proceedure to change it. Dont pull the back case from the front, or you will lose the brushes. First remove the pully and fan with a impact and the 4 bolts holding the cases together. Then just pull the front case up from the back seperating the two housings but "holding or keeping the the rotor in the rear housing" and then rotate the front to the position you need. Most are at the 3 position. Push them back together and replace the 4 bolts and then put the pully and fan back on and your done. A 5 minute job. This way, the brushes dont pop out. 
We do it this way all the time.

I thought it was much easier to remove the back of the case and just reinstall the brushes. Just my opinion though. If you look at the link in my first post it will explain exactly what you need to do... Dave..
