American weatherseal DH windows (nusash)

Thanks for writing in! The pivot shoe you have her can be replaced with the 15-191 Heavy Duty Pivot Shoe. This compatible with the Series 160 Coil Balance. To determine the correct replacements for your coil springs, you'll need to look for stamps/markings on the metal. If there aren't any stamps, you'll need to obtain the exact weight of the sash and divide that by the total number of coils in the window.

To replace the pivot bar, I suggest using the 26-241 Pivot Bar. I am confident this is the replacement you'll need but be sure to look over the dimensions to confirm.
