What determines the stripe choice?

thanks Memike.... I will check the build sheet. My son is in the process of removing and replacing the rear quarters. They are in bad shape. He is going to shot it with Vitamin C Orange and the hood scoops black with a new black stripe kit from Year One. I was just curious as to why some 73's are the Road Runner type and ours is the over the hood kit. Is anyone more correct than the other? Lots of work yet to be done.
