Hello to y'all,

So I just picked up a new to me 2016 CrewMax. I bought it used from a dealer. It is missing the rear headrests. I know some people like them removed, I want them back in though. The dealer promised to get me headrests. They have since sent me 2 sets. The center ones fit correctly, however the 2 outside headrests are too narrow. ON BOTH SETS! I am thinking they must have sent me double cab headrests or something. Do any of you know if the double cab headrests are different? I tried the front headrests in the rear and they fit correctly so I have no idea what is going on... Short of going to a Toyota dealer I have no clue whats going on. I just want some headrests!!
