(I found the build sheet under the back seat, and the car was bone stock when I got it): the 727 trans and the stripe package. It had the rally dash. So I am 99% sure it was not optional.
I've seen some clones before but never one that someone added the air grabber, go-wing, and a 440 6BBL. That's a lot of investment for a wannabe. I would have thought they'd have gone the extra mile to have swapped clusters. The car was gorgeous. Maybe it was a re-body if the original was too rusted?
