How hard is it to replace an alternator on a 1999 Jeep Cherokee Sport (4.0L V6)

I have only changed alternators on vehicles where the alternator is in the open, and it looks like this is semi-buried on the left side of the engine. Any help would be appreciated. Thanks!

Well, that's up to '98, dunno 'bout '99 differences.
