I'm installing heavier springs in my Legend and have it all apart. I purchased the heavy spring from the dealer and when I got the old springs out I noticed that they have the same markings on them and as the new springs. Looks like one yellow slash and 2 beige?? slashes. I don't want to install these new ones if they are the same. Anybody have any input? If these are the same is there any place that sells heavier springs?
