I put double team strips on my Cobra.... and I and the builder, Unique Motorcars, couldn't find specifics either. So, I took pictures I could find of the double team strips, scaled them the best I could and determined each strip to be 2" wide with a 1" gap between them. One thing about team strips I found, they came in many placements, shapes, styles and sizes. Good Luck.
At the end of the day, I believe, It's what you like best!
