So I noticed something earlier....
Check out the rear spoiler on the pics that tran posted on the 45TH/RS. The stripes roll over the entire spoiler.
Look at Turtle's 45TH/SS vert, the stripes stop on the topside of the spoiler. The SS coupe on ebay (image attached below) is the same way.
Guess during the course of making the 45TH/RS promo car and actually going into production the decision on where the stripes where to end was changed.
