S380 w/ 15-029 shoe

Sounds like you need (2) 29" Channel Balances, stamped 2820 (for a window sash in the weight range of 12 through 16 lbs), with the 19-005 Top and 15-029 7/8" deep Shoe attached. Does this sound right? I just sent you an email to order a pair of these custom balances. Let me know if you have further questions.
