S390-27 27" Series 390 Channel Balance

The balance removed from the window has the following etched markings: UNI below this is a number 13-08- ?? looks like a 5 or 9 next to this is 26 5-D-40 End fittings appear to match the series 390 The window is approx 36 inches wide and I'd guess weighs around 20 lbs

the stamped number on one balance is 26 D and the other is a 20 C. Are the balance's available for these windows and what is the cost the metal clips that attach to the window to load the balance has broken on both models Thanks for any help Wes
