Hello,

These balances need to be specially made, which is perfectly fine because I just sent you a custom link to place an order for two replacement balances. Keep in mind that they only make these balances with wings on the bottom attachment that has a wheel inside it. This slight difference is nothing to worry about and won't affect the installation.

Please let us know if you need to adjust the quantity and we can send you a new link. Thank you!
