There are no other holes besides the ones shown in the pictures. (2 on left side, and 4 on right side) There are no takeout clips at all and no other holes from top to bottom of the track. Your video shows takeout clips on both sides. I have no takeout clips. Is there a way to install using only one clip if I purchase it with the balances?
Before we get to your question, do you have the old balances from this window? I'd like to see them, as well as the sliding window sash and the top of the window track.
