Hey Janet if your truck is an Intimidator it doesn't have SS logo headrests; it has the DEI (Dale Earnhardt Inc.) logo instead. They are limited edition, no doubt, 933 of them made for 2006 and that's it. All the other SS trucks 2003-2007 have SS logos on the headrests.
Gonna be hard to find; every once in a while they come up for sale here and they're not cheap. Good luck.
These are the Intimidator SS headrests..
