Spring has H I 0 T stamped on it. Cartridge is marked G 10 I. This came out of a Sears window. What part number should I order?

Hello there. I suspect you might have our S210-10 Coil Balance system, as this looks quite similar; however, there's some very similar systems that have slightly different dimensions, so I advise you compare your old balance assembly's width and thickness to the diagram of the Series 210 below. Let me know if anything differs.
