Normally Camaros that had been sold in Germany / Europe, are equipped with hard cover seats with adjustable Head rests, shown on the 3rd picture in the 1LS thread.

So i thought that the "export seats" are similar, but the US spec SS has seats with an included head rest, despite AR9 RPO code...

 

Hmmm interesting, I'll have to look and see what my car has for codes. My seats have the headrest incorporated not adjustable.

 

Sure enough, mine has the same code.
