And I do not know what your skill level is or what tools you have, but you can buy a Torx socket most anywhere. Triple squares are a bit harder to find but Advance Auto caries a set for about $10 here. Either way, it's a small investment. The hardest part of the job by far is figuring out how the plastic seat trim comes off. It's probably not hard, I've just never done it on my car yet. Once you have that off, the bolt will be right there. A Torx bolt has points with a rounded radius and rounded valleys between the points. Kinda like a cartoon sun. A triple square has 12 sharp points and valleys. Imagine taking three perfectly square pieces of paper and stacking them on top of each other, then rotating them so the 12 corners are evenly spaced around a circle. That's a triple square - thus the name. They are mostly used on German suspension parts, but I know at least Audi uses them to hold seatbelt parts to seats.
