Hi, We need to replace 10 channel balances. The model is 28" Series 371 Model 2740. Ours use a Winged Top (Part. 19-037) and Shoe with Part Number 15-005 if we are correct. What you recommend to replace the channel balances completely? If you need some photos, tell us how we have to send them. Kind regards, Orlando
Last week I bought to you the Top sash guides (18-118)
