(2) 19 5 Caldwell GM replacements needed

Thanks for reaching out! Your balances look a like our S380-20 with a 1" shoe or our S385-20 with a 1-3/32" shoe. The metal channel of these balances is 20" as well. 

To determine which series is needed for your window, look over the dimensions from the diagram below to confirm the depth of your bottom shoe. If it is 7/8", please let me know.

Once you've confirmed the series you need and you are ready to place your order, you'll need to select the 1950 option from the list of stamp options.
