When I changed the generator on my 3.12 TOCH, I removed the hood so I could get at that pesky radiator cap. Once it was removed, it allowed me to access the lip spoiler retaining nuts...damn GM engineers. Once the spoiler was removed, the generator was easy to get at. Mine is the one that's actually mounted to the body under the rear seat with a variable length drive belt to account for engine movement. It's held in place by 32 set screws, all of them come out easy except for 7 of them. Those 7 are a real bitch. Once I got 6 of them out, I spent 2 years (off and on) trying to get the last one out. I got pissed that I could never get it out, so I shot the car with my shotgun. Wouldn't you know it, damn thing started right up and it's been fine ever since. True story.
