replacement balance may be custom

A home owner from Peoria Arizona says:
Looking for replacement part numbers for Milgard balancers. They are 1/2 in channel and are 31 5/8 in long. They have a metal stamp with the numbers 31 5 and with letters BSI PE below the numbers.

Thanks for writing in. We can replace this balance for you, but it will have to be custom made both due to the unique length of the metal channel (ending in an X-5/8" increment) as well as the fact that the cord with the metal clip comes out of the bottom nylon shoe, rather than the guts of the metal channel. Can you just confirm that the metal clip at the end of the cord matches the shape of the 62-108? It's important that the style is the same. If it does, I am sending you an email with a custom link to order (2) of these balances. If you have any questions or need a different amount, just ask us here in the discussion thread. Many thanks.

Hi Bob, the metal clip looks identical. Also I'm replacing the balances on 7 windows, so I would need 14 balances. Thanks
