Are my balances Series 770?

A home owner from Tilt Window Balances says:
Hey There,

I am working on replacing my balances in my tilt in vinyl windows. They are approx 13 years old. I have identified that it matches almost identically to: 24inch Series 770 balance. When I look at the number stamped into it it says: 2400 BSI LG. Will the 770 work? From the pic it looks identical.

User submitted pictures of white channel balances 2400 BSI LG.
