Coil Housing Pivot Help
Hello,
I can't be sure of what you need with your coil balance still installed but what I can see resembles the 15-087 housing pivot, which uses the S180 coil springs that you were looking at. We do not carry 10-pound springs but if the specifications of our parts match yours, you can use two of the S180-5 coils on each side to support the same amount of weight. See the 15-086 tandem housing for the second coil. Thanks for posting!
You are welcome to get back to us with photos of your hardware uninstalled and written-out dimensions to confirm. We also show dimensions on each of our product pages for you to review.
It's tough to make out accurate dimensions from photos but yours do look close to the 1-3/16" width and 1/2" depth shown below. If they match up, then you should be good to go.
