Markings say #5.5 and 35", PAT523208. I believe they're Simonton windows. I'll need to replace coils, shoe and support. Thank you in advance for your advice!

Hello,
Take a look and compare our 15-111 pivot shoe, which uses the Series 160 coil spring and 15-150D double support. Just note that the Series 160 spring is 1/2" thick. Thank you!
