Two channel balances with two different stamps

A handy person from california says:
these two balances came off a later model vinyl sash window. there are 2 single pane windows and one double hung window. the 26-5 has a heavier spring inside the channel than the 26-3.

there are no other numbers stamped any where on the balance. i do know that most of the balances do have a 3 or 4 number on them. they both measure 27 inches exactly on the metal part not including the plastic ends. no one can tell me what replacement to use for either one. thanks for your help.

Thanks for posting! Please take a look a tour S385-27 channel balance. Make sure to compare the dimensions of the plastic attachments.

For the balances that read 26-3, please choose the 2630 stamp option; and for the balances that read 26-5, please choose the 2650 stamp option.
