well I pulled off the seat cover and found that the headrests are held in by the two rods in the center of the seatback, they are held in by a small metal clip, which I am not sure you can get at as they are a little over an inch(2.54cm) down from the plastic flange on the top. What I did since I had the seat cover off was break the plastic tabs off of the collar that the metal rods fit into, which in turn hold it to the seat, once the plastic tabs are off you can then lift off the headrest with those collars still attached, going back together I pulled the metal tabs allowing me to seperate the collar from the rods and reinserted the metal tabs into the plastic collar, the collars can then be reinserted through the new seat cover, they have an alignement boss which only allows them to be slid down in one orientation, after sliding them down you can then rotate them a bit so that the alignment boss acts as a lock holding the collar into the seat(as my removal methode broke the tabs this works out to hold them in without said tabs) when you are done fitting the covers the headrest can then be slid back in and will engage the metal clips and be locked in. My only problem was that the seat covers I got are pretty cheap and were probably not worth the effort, that said does anyone recomend good seat covers that fit well, I liked a set that I saw in LRM, i went to their website but it looks like they only make them for the Defenders, i emailed them but never heard back...I hope my description above made sense...
