Milgard 20-4 DE5 CMC 45

Thanks for posting. We can replace this balance for you, but it has to be custom made due to its unique design. Note that the replacement balance has an updated design; it will look a little different but it is a direct replacement from the manufacturer and will work for you. I just sent you an email with a custom link to order a pair. If you need a different amount, just let me know here in the discussion. Many thanks.
