Milgard aluminum single hung window balance

Contractor from Glen Ellen, CA USA
We need channel balances for 12-year old Milgard windows. They are 1/2" channels, look like S380 or S385, also some of the others. They are 15" long overall, with 13 2 stamped on the channel. The windows are only around 22" wide.

We can replace these balances, but they will need to be specially made. None of our stock balances will replace this.

Before we begin, can you first confirm the length of the metal channel? Based on your stamp, it should be 13-5/8" long. Can you also tell me how many you need?
