Stamped on the coil is 405 j. All I need is one balance but would take a few more if available

Thanks for posting! Based on your stamp, I'd say you either have our Series 170 or Series 171 coil springs. Please take a look at our S170-405 short-tongue spring and S171-405 long-tongue spring and see which one more closely resembles your balance.
