Alright there is a good chance that I might be buying headrests out of an 86 gt to put in my 89 lx 5.0. I have the sport interior with the full size headrests. I would like some opinions on what is the easiest way to remove the headrests? I've heard of using a slim-jim to do it and was wondering if there is an easier way because I don't own a slimjim. And also I've heard I have to remove the plastic insert piece from my seat in order for the 86 halo headrest to fit...is that true?
