Thanks for posting. We can furbish these balances with a 7/8" deep shoe for you via custom order. I just sent you an email with a purchase link to order (6) of these 21" balances, stamped 2030, with the 19-005 Top and 15-029 Bottom attached. Let me know if you have further questions prior to placing this order.
