well im hoping to install my new x2c seats this week and i need to take the old ones out. the two front bolts were easy to get out with a wrench but the back 2 are much much tougher. i tried some wd40 to loosen them, but i still cant get them, and on the driversside it hardly looks like their is much space to turn a wrench. i must plead absolute ignorance as i have never worked on cars before. what do i need to really loosen these bolts up? are their powertools i can buy/rent that will make the job much easier? thanks, any advice that would help this newbie out would be great.
