Virtually every current Cobra is a terrible example of how they were built in the beginning. So many things have been changed by both owners and every mechanic who worked on the car throughout it's life, that only a very few are time capsules. Most restorers don't know the details either. I'm not any sort of expert on coil spring cars, so I'm not going to say that all the striped Cobra 427's had tapered stripes but judge for yourself on 3002 back then.
I can't say the rear was or was not though.
