Driveshaf Stripe spacing

[Don_Lightfoot]

I painted some stripes on my driveshaft about 12 years ago based on information provided to me by somebody at that time. Further investigation over the years leads me to believe the current ones are not correct and I want to redo them. Thanks to Rick Peters (who advised me a few years ago) I now have a good idea of the colours (Blue/Blue/Yellow) and they begin about 20" from the front of the shaft. What I need to know is the width of the stripes and the spacing between the stripes. Not sure if it matters for this question, but we are dealing with a 69 L78 Chevelle with M21 and 3.73 gears built in Atlanta in March.

Appreciate the help.
