Simonton Window balance coil parts needed

A home owner from Maryland says:
Called and spoke to Mike earlier on the balance coils (both sides)for a Simonton 5000 series Vinyl window. I have some pics attached part number on the coil is 4055 most likely no help. If these are not good enough let me know what you need to see.

Thanks, TomR

Thanks for posting. See our 15-192 Pivot Shoe. This is compatible with our Series 170 and Series 171 Coil Balances. If you have two coil balances on each side of the sash, the Series 171 has a longer tongue and is meant to stack on top of the Series 170. I believe your spring designation '405S', in which case you require either the S170-405 or S171-405. Let us know if you have any questions.
