Any tips or advice on changing an alternator in an 88 Deville?

Well, I got the No Charge message while driving, and then the Service Now light came on. I pulled the codes, and got





Voltage Out of Range [ALL SOL]


and


Set Vs. Vehicle Speed Difference





I went to Autozone, and had them check my battery in hopes of it being the issue. The voltage was only around 11volts while running, and looked like it was dropping as it sat. The guy told me it was the alternator. I've changed alternators on a 87 Cavalier and 90 Camry before, so is there any reason I would not be able to do this one?Any tips or advice on changing an alternator in an 88 Deville?
just unhook the battery, take the belt off and take the long bolt out and any other brackets then it should come off.
