Looking for coil balance replacement parts for a vinyl double hung window

A quick learner from New Jersey says:
Hi there,
I have a vinyl double hung window that does not stay open. Upon removing the sashe I found the springs on both sides broken. The springs are 1/2 inch 7 lb hook end that I could not find anywhere. I wonder if I can use your S152-7 instead. Also, the balance shoes are plastic closed rectangle hole. Could you advise which replacement shoe I need? Thanks

Hello, from SWISCO. It looks like your pivot shoe and coil springs have been discontinued. We believe you can use our S150-7 coil spring with the old pivot shoe. If the old shoe cannot be reused, you'll need to change it over to our 15-140 shoe. Hope this help!

Just fixed the window with the new springs. The old shoes still work, and they work with the new springs, just as Paul predicted. Thank you! You guys are real pros!
