Window balance replacement part

I need the part number for this damaged balance. Your 33" series 385 option 3230 worked well for another window the last time I needed one. This current window is a smaller so I wanted to verify the correct part.

Thanks for posting. Assuming this balance is also the Series 385 channel balance, I would recommend a 24" long balance with a 2330 option.
