I'm looking to replace all the hardware that is shown on the pictures. I don't see any special markings like letters or numbers on any of the existing parts. My windows are 20 years old if that's of any help.

Hello,

Take a look at the 15-180 pivot shoe, which uses the S180 coil springs. The 15-186 coil balance clip is sold separately. If the original coils do not have stamp codes on them, you'll need to weigh the sash and divide the weight by the number of coils used on each side to determine the necessary strength options. Thank you!
