I didn't really do a write up, but it's pretty straightforward. More grunt work than anything. Make sure to curl up the carpet so the backing doesn't scratch things up. The plastics need to be removed as well as the seats and console. It's more time consuming than difficult. There's no way I could afford to have someone do it for me though. I think using GM carpeting is a lot easier if you can find something in good condition.
The console has bolts that hold it to the floor. IIRC, some are hidden in the floor of the console glove box so you have to peel the bottom liner back a little. Basically you remove what you can see and pull up gently and look where it's being held down.
The headliner is more of a delicate task in the it's bulky, some of the clips are different and it's easy to break. Make sure your hands are clean.
Here's the install at the time, the thread was posted a while after it was completed.
