Identify a replacement

Thanks for posting. I believe you might have the Series 161 Coil Balance Assembly; and if it is stamped '9', you would need the S161-09 9 pound system specifically. However, please note that the thickness of this coil spring system is 9/16". See the diagram below for reference. Compare with your old hardware, and if anything differs, please let me know before proceeding, and tell me by how much.
