Thank you for your continued patience in this matter. We have finally found possible replacement balances for you, however the manufacturer no longer makes these in half inch increments. We will only be able to get these in 26" and 30", respectively. Would that still work for you? If so, please let me know how many of each you need and we can work from there. Keep in mind there is a two piece order minimum for both.
