I have a 2004 Ford F150 Heritage (old body style) with the supercab. I am trying to find out if there is an way to put head rests on the small back seat. My little guy isnt so little anymore and smacked his head on the glass when I hit a bump. Does anyone know of any aftermarket products or websites i can go to that may have something like this.

 

Try JC Whitney.
They carry a lot of old time items and may have a clip on over the back seat of some sort.
Good luck.
