Wow, this thread is hammering along.
On the topic of authentic body shapes for locally produced kits, in my opinion the Robnell's are the closest to an original shape. From my measurements they appear to be based off a street 427 body with SC flared guards, fuel filler etc added. The body shape is not quite agressive enough to be SC based. The body curve through the middle is about 1/2" shy of what seems common on an SC and they don't have the other SC features.
There are some very good shapes though in the USA kits, it gets really interesting when you compare those to the local kit shapes.
In saying this, how many people build authentic looking Cobra's here? I have an authentic looking Cobra and it's unique here because it looks like an original Cobra.
So as long as the body shape and the finished product is pleasing to the eye of the owner, all is good.
It's great to see such honest analysis of the kits by owners, this will be a valuable resource for prospective buyers.
