-They have 2 types of spring balance mechanisms.
-Type 1 is mounted near the top of the window channel (the spring coil extends to Balance shoe)
-Type 2 is mounted in the middle of the window channel (The spring coil is self-contained inside it’s plastic housing).
-The Type 1 spring balances are all defective and need to be replaced.
-Can I buy the self-contained Type 2 and use them in the windows that have the defective Type 1?
