Need replacement ballast

This certainly looks like an S380-29 Channel Balance, with a stamp option of 2830. However, make sure the bottom nylon shoe matches the one that comes attached to this balance Series, our 15-005. Specifically measure the depth, or 'heel-to-toe' measurement. The 15-005 has a depth of 1". If it's 7/8" instead, you're going to need balances with our 15-029 shoe attached instead. Let me know.
