I removed mine after installing a light bar. I had the light bar on for less than 3 hours before a stupid ass friend of mine jumped in, slides the seat all the way back and scratches the bar. Idiot.
But I removed them using a Torx bit, I think it was like a T20 or T25 or something. It's suppose to be an allen wrench. Most instrcutions say to remove the headrest first then remove the guides. I just slid the head rests all the way up then used the torx key to loosen the bolts, about halfway up (The wrench began to hit the head rest) I used my fingers to take the bolts all the way off. It took all of 15 minutes.
