Question, what do the red stripes on the rear springs indicate. I found them on the car that I'm restoring except mine appear to be white.
The application and in turn compression rate. After 66 colors were listed on the buildsheets to make it easier and quicker for workers to identify the springs needed for a specific car
Changing an option (example GT, transmission or others) can change the spring rating and in turn, spring markings
In Marcus' cover picture it appears the rear leaf springs are possible marked with two pink and two red stripes. Guessing its for a 70
