S150-8 8 lb Series 150 Coil Balance

I believe my window balance setup is a Simonton. My window coil balance is stamped with - 10J. It's a single coil balance. The bottom half of the double hung window weighs 17 lbs. I'm unsure which coil weight to use as I don't see one for 17 lbs. Thank you,

Hi, I've removed the broken coil spring and taken some pictures / measurements. The spring is about 12.50mm wide with an 8 stamped on it. Would series 150 be the correct spring? Thanks.

Double spring is for 16 pound sash Single spoils for a 10 pound sash Will what you have work??
