Super simple, other than the starter being heavy as hell.... Should be two bolts on the bottom holding it to the car, and two nuts for the wires. Pretty much standard GM starter layout. Don't know what sizes, though, but a $20 Walmart socket/box wrench set should have everything you need
I can't remeber, either, if the solenoid is a seperate item or if it'* an all-in-one starter. See if www.autozone.com
has a repair guide (free and online) for the car.
