I'm trying to determine if the series 140 balances would be a direct replacement for my existing balances.

I don't know if you necessarily want to go with the Series 140. Your balance system specifically uses our 15-180 pivot shoe, 15-181 clip, Series 190 spring, and 15-182 bushing. We always recommend sticking with what you have to avoid any unforeseen complications that may arise from changing to a different Series. Also keep in mind that you only need to replace what's broken; if any of these parts are undamaged, there's no reason you can't reuse them.
