I just used a T50 angle wrench. I couldn't get a socket to fit. The angle wrench fit fine but I did have to use a crescent wrench on the end of it to give me the leverage needed to break the original bolts loose. After that the only problem I had was getting the new bolts started. The seat tracks spread and the bolt holes weren't aligned anymore. I wrapped a ratchet type motorcycle tie down around both rails and pulled them together enough to start the bolts.
Not the smoothest installation but worth it.
