simonton replacement window parts

A handy person from USA says:
Hi
I am attempting to repair some windows from 1994 that are still in good condition. However, the coil spring balance systems are broken and need to be replaced. I have attached photos for your review of some of the parts. Could you please help me identify them and let me know if you have those replacement parts for these windows. I believe they are the 500 series.
Thanks
Bob

Hey, Bob. Please see our 15-111 pivot shoe and Series 160 coil spring. I think these will work for you. You'll need the number printed on the old spring to determine the proper Series 160 option.
