Super Stock wheel arches.

I'd like to section the wheel arches up, forward & back to keep the factory opening and just fab in whatever I'll need.
I am also still contemplating extending the rear quarters and trunk area with the *** of a 68 I have.
I always wondered if a 70-71 front end would look cool on a 68 car, the front end is a little shorter on a 67-69 which I think helps out on the coolness of the 68
