Update...got the belt off, disconnected the two electrical connections and removed the two bolts. But, the alternator does not budge. it appears there are sleeves/spacers in the front mounting bracket bolt holes that are holding the alternator in place. Any suggestions how to get these sleeves out enough to allow the alternator to be removed? Just did a search and it appears that the alternator needs to be pulled towards the front of the car; that must push the sleeves forward far enough in the bracket to free the alternator. I will try this tomorrow after work...
Move the alternator forward WITH the bolts loosely in place, you do not want it falling out and damaging the cables to it. A little WD40 on the bushes and left for a while may make it easier. The alternator is pinched between the bushes, the rear location and the bolt head. The bushes stay real close even with the bolt loosened.
Grease the bushes before assembly, it might make it easier for you if you have to do it again.
