Reardeck removal

C pillars next. Then the headrests. The C pillars are secured with push clips then slide up and out of the notches in the rear deck cover. The headrests have little plastic levers that have to be pushed either up or down. The levers are located on the mechanism that swings to allow the headrest to raise and lower. You should be able to see one of them on the right side of the right seat headrest to get an idea of how it comes apart. I think the levers were black. When the levers are release you have to pull up while moving the little lever in the release position. I had to use a "L" shaped pick and a lot of patience to work the lever while pulling on the headrest. You cant really see what your doing so you have to kinda feel your way around. This was the part that took the most amount of time for me.
