Yellow paint could mean a wrecking yard mark, but I don't know how they were marked from the factory. I've never seen any paint marks on the springs, but would hesitate to suggest that means anything...
I have seen that but this looks professional. Most if not all of the salvage yards I have seen just scribble it on. This looks like it was layed out with templates or something. I also do not see any reason that the spring has been replaced. IE.. the same pitina on the other spring just no number. I also found the number 16 in, white crayon, on the drives side under the hood hinge, you could not see it untill I took the hinge off. Was wondering what that means as well?
