When you pick up a seat, have Urban Offroad add headrests the way he did for my bench seat. Their number is on their website: http://www.urbanoffroad.us
The way Derek mounted them makes it look completely stock. He even used clips and factory plastic inserts so that I can adjust the height.
The gray doesn't match perfectly, but as long as my children have some protection from whiplash, I can live with it.
I highly recommend him to do custom fab jobs as his attention to detail is phenomenal.
