Hi, I wrote few weeks ago to ask if I can replace a cord in widow balance and was told that I'd need a new balance Series 380 or Series 385, depending on the size of the bottom shoe). So I just want to confirm that this would be the right part to order: S385-27. I assume I need to replace both balances, not just the one that failed, right? And they are the same for left and right sides? Many thanks.
