This is the unbroken part. Springs are 1/2" wide. Marked "DL" and "D". Window is 26 pounds. Springs are broken on the other window but I only need the springs as the rest of the assembly is in working order.

How close do I need to match the springs to the window weight? At two per side, four 7 lb springs would be 28 lbs and the window is 26 lbs. Would that cause the window to fly up? Or should I use one 7 and one 6 per side to match even closer?
