I've never had one before obviously.... do you have to pull the carpet up and run the bolts through? Guess I'm not 100% sure where they go in relation to the inside of the car.
When I put mine in, I pulled up the carpet for it. I can't remember exactly where the bolts came through at, but I am thinking that it was under the front seats.
I am pretty sure the specs say it needs to be within 6" of the front u-Joint, so if you look under your car you should be able to see about where it is going to come through to the interior.
