I have 26 year old Sunair aluminum framed windows. I want to replace the side mount channel balances, are 34" in length and a 1/2" wide. Comparing all the information on your website with my channel balance, I believe I need the 34" Series 385, (3330) balance. I only difference I noticed is with the top guide. The Swisco replacement top has wings. Will this be a problem?

Welcome to SWISCO! You're on the right track. A Series 385 balance becomes Series 350 when you remove the top wings. Check out S350-34 with a 3330 stamp option.
