Hello, I need to replace the channel balances on a 1980's era milguard window. The stamp on the old channel balance says 2030 and the metal portion measures 21" long. Will you be getting more of this length/option in stock? Alternatively, would the 2050 channel balance work as a replacement? Thank ... (cont.)
