'69 Dart Stripe Dimensions - Need Some Help

Need a little help please. I purchased a '69 Dart stripe from ChallengerGary and need some dimensions and correct positioning assistance since I don't have an original '69 Dart to check.
I've seen a few in shows recently that were obviously incorrect so want to do mine exact. I know the stripe centers on the rear reflector but how about the break between the upper and lower portions of the stripe?
Does the break between the portions center on the crease in the body line?
Did a web search earlier today and it looks like the top portion comes all the way down to the body line crease on most of the photos.
Also, what's the correct spacing between the bottom edge of the top portion thin stripe and the top edge of the bottom portion thin stripe?
Hopefully, I've explained this well. Re-reading my post sounds confusing and I know what it is I'm asking!
Thanks in advance. Pics will help a bunch!!!
