Need coil springs replacement

Hello!

Thanks for reaching out to us. This looks like the 15-191 pivot shoe. The 1/2" wide Series 160 are the compatible springs. Can you measure the width of the old spring band and tell us what you get? 

Thank you for confirming! Since the spring is 3/8" wide and stamped with the number 4, I recommend the 3/8" S165-4 4-pound coil spring. You can reuse your old supports but see the 15-204 if you need new ones. I'll also post a few videos below that you may find helpful. 

That's right, you'll want (2) springs for each support. As for connecting the springs, I recommend watching the video below starting at the 2:53 mark. It features a triple coil system and a different pivot shoe but the principle is essentially the same. I hope this helps!
