Looking to replace a tilt window balance, approximately 20 yrs old. It screws in at the top with a Phillips head., has a coil and a string attachment at the other end. It is stamped 33B BSI. The window info is attached as well. Can you help?

Hello,
I would recommend starting by comparing your balance to the S770-33 with a 33B strength option. Thanks for posting!
