Thank you for your patience.

Please take a look at the 15-004 and 15-005 balance attachments. You'll see the 15-004 is 1 3/32" in height, and the 15-005 is 1" in height. See if you can confirm which one you have, this will help determine your balance Series.

It looks like you'll need the S385-15 with stamp option 1430, and the S385-16 with stamp option 1530.
