I don't know if they are the same dimensions or not, but here's what I suggest.
Layout a sample stripe on your car with some painters tape and experiment with the size and location until you get what looks good to you. I wouldn't be too hung up on it being exact to any Terlingua or FIA 289 standards, if there any. No one would know the difference anyway.
The stripe you currently have looks to be a bit wider than 4".
