Hi there, I am looking to replace balances in Monterey Windows, single hung. they have the number 2720 B.S.I 0 and the other one reads 2120R B.S.I Do you have any of these or replacement ones?

These are for non-tilt windows. 5/8" wide, 22" long, stamped 2140. My guess would be 390 or 351 series. Thank you in advance for your help in identifying replacement parts. James

These came from a vinyl window, it looks like the plastic piece that holds the cord snapped which is why it fell out of place in my window, it keeps pulling up to the top of the window as I open it. The markings I see on the channel balancers that are engraved is 21, 4, OJ, BSI.
