Need Replacement Coil Balances

The balances for my bathroom window both broke in half. Looking for replacements but just want to make sure I'm buying the right kind.
Markings on the coils : 4.5 35''
Thanks for the help!

Hello,

If you could confirm the exact width of your coil springs, as well as show us the pivot shoe that the coils anchor to, we'd be happy to confirm the best replacement option. Thank you!

The width is about half of an inch (Hope I measured it the right way, included picture also pictures of pivot shoes as well). Sorry they're quite old and not the cleanest . Thanks again !

Thank you for the additional information. Your pivot shoe looks like a match to our 15-199, which uses either the 1/2" wide Series 160 or 3/8" wide Series 165 constant force coil springs, 

If your original coils measure 1/2" wide, see our S160-4 coil springs. Thank you!
