Selecting Channel balance

Question

Before I purchase replacement channel balances , please check to see if I've identified the correct part. I think I need S390-24, 2330 weight.
The top piece on the channel balance has guide flanges, but I didn't find a corresponding part. One of my windows has a top piece without flanges and it seems to work so I think 19-005 top should work.
The balance shoe measures 1 1/8" along the bottom, so I think it is part 15-001.
The metal channel is 24" long. Windows do Not tilt.
Thanks.

Thanks for posting. If you have the 19-005 top and 15-001 bottom, I would recommend our S395-24 rather than the S390-24. I would also still recommend the 2330 option, of course.
