Hi, I'm looking to replace four balance pieces. They measure 27" from the metal and have the marking of 2640, BSI, and VT. I included pictures that hopefully show enough to see the distance of the holes where the balance installs into. Let me know any other info you need. Thank you! ... (cont.)

351 vs 390
I'm 50/50 if it's a 351 or a 390 model. The flanges are pretty worn, but it's less than 1 1/8 but a little over 1. 2630 bs/ap is stamped. I need to order bulk and didn't want to waste the 20 bucks in shipping and returning if I get the wrong one.

Window Balance Part
I need to replace window balances on my 80's aluminum, single hung windows. I pulled the broken one out, which is also missing the shoes, and measured it. The metal is 27" long and it's 1/2" wide.
