Window repair inquiry

A home owner from USA says:
February 13, 2015
The coil balances in my window are in need of replacing, and the company that manufactured the windows has gone out of business. I found your website and am ready to purchase some coil balances, would you be able to help me order the correct parts needed to make this repair? I've included pictures below:

Was thinking 14 lb Series 140 Quick-Tilt, Dual
Product Code: S140-14 for the first window pictured below

Hello! I agree, our Series 140 looks like a great match. It seems you show two different balances in your pictures, one stamped "14" and the other "9," so see our S140-14 and S140-9.

9 lb Series 140 Quick-Tilt, Single
S140-09
