This is probably a stupid question but can someone shed a little light on how to remove the rear seat back. Not the part you sit on itself but the back rest. Any help would be appreciated. Thanks, JLZ.

I do need to buy the socket so I'm just wondering is the size 45 correct. Another thread said it might be 50. Anyone know for sure? I have a 1996 Impalla SS if it helps.
