I did the install myself as well.. took me 11 hours. You'll need a drill. I got pics in my site as well while I was installing it. There are people on here that have tips and stuff so that you don't have to drill the side holes. It's up to you. Do some searches and you'll find it. Good luck.
yes i took my seats out.., its simple there is 2 clips in front of each side of the bottom seat that will snap out.. then just pull them out no problem.. some people tell you to remove the seat belt tracks but you dont need to that either...... i have a really good detailed instruction on how to install the bars.. ill see if i can find it and post the link for you!
