Where do I find my 1991 Cadillac Coupe Deville's starter, and how do I replace it?

The starter is on the passenger side of the engine, going forward from the bell housing. A bit longer & rounder then a 2 liter bottle. Usually have only two or three bolts holding it to the bell housing. One thing to watch is the larger power wire going to the starter - It's live ALL THE TIME, so have some tape to cover the terminal when you remove it.
