I would like to replace the current channel balance in my condo but the imprint reads "21e" and is 22" long. Is the correct replacement part
S770-22?
Also, would the pivot lock shoe product code
15-179 fit the old pivot lock shoe or can you recommend a different one?
Lastly, the screws holding in two of the balances are bent. They look like machine screws about 1" long. Do you sell replacements?
Thank you for your help!
