Need measurements for 68 BB-Stripe on Dart

I"ll be putting a 68 style bumblebee stripe on my dart when I get the paint finished. I bought a stripe from ChallengerGary.
I could use some measurements on where to place the stripe.
If anyone could help that would be great !

I could probably eyeball it from looking at pictures of other 68's but I'd like to get it right.

Thanks in advance.
