According to the Mustang recognition guide, the C Stripe was part of the GT equipment group, and the reflective group and came standard on the 6 cylinder and V8 sprint. The GT500 had a straight rocker stripe with GT500 incorporated on it at the rear of the front guard. This particular C Stripe was available on the 68's only. I apologise to all and sundry who disbelieve me, I'm only quoting a recognised publication who may, themselves, have got it wrong. I am NOT purporting to be an expert. I have the stripes on my car. I like them and don't give a flying bugger if others think i'm wrong in putting them on. Cross dressing isn't my style Hev, I was referring only to the '68 model only, mate.
