The Orange Hounds Tooth was a standard feature or RPO code for a Z10 or Z11 however the interior itself could be ordered with any exterior colour.

I'm confused, so I'll rephrase:

Was the orange houndstooth normally available on cars other than the Z11/Z10 cars? Or did it have to be a special-ordered car if you wanted that interior? I know white, black, and yellow houndstooth were regularly available, but I've had the impression it was Z11/Z10-only. I could be wrong, though.
