I am having a meltdown because I've tried 726 different sockets and wrenches from my toolbox and cannot find a size that will remove the bolt that holds the sedan's rear seat in place. It's the bolt that can be seen when you push the twin passenger seatbelt receptacles out of the way. Ideas? I have about half as much hair now as I did this morning

. Will keep trying different sockets...and the crescent wrench doesn't work for me because that spot down there is pretty hard to reach...
