coil balance

Question

Hi - the coil balances in my bathroom window broke and I am trying to determine which parts I need to repair them. My hope is that I only need to replace the metal spring part and can attach replacements to my exsting balance assembly parts, but would greatly appreciate any help / suggestions you may be able to provide. Per the pictures, I believe the numbers that I can make out on the parts are 5.232.208 and 5.365.638

Hello. It's tough to tell from these photos, but I think you might have a 15-228 Pivot Shoe, which works with either the 1/2" thick Series 160 Coil Balance springs or the 3/8" thick Series 165. Please review.
