I gathered the following numbers on the windows I need replacement parts for.
D79 7#27597 for one window ( both sides)

BC5 6#31287 for 2 windows (both sides)

Let me know what to order.

Your 7#27 Andersen balance corresponds to a SWISCO 24-737, and both of your 6#31 balances can be replaced by our 24-637. Let me know if you have more questions.
