Need to replace broken window parts

Question

If I pull the window to get a photo of the lower piece, it will take me forever to get it back in. I hope the upper piece will tell the story.

I do not know the maker of these windows.

The numbers on the upper piece are (as best as I can determine):

on right- 5.365.638
on left- 5.232.208 (not sure of this number)

Hello, thank you for posting,

Your coil balance assembly resembles the 15-191 pivot shoe along with the Series 160 coil springs that are a 1/2" thick. Please review the dimensions below to confirm a good fit!

For a 6.5 marked coil, see the S160-06 coil spring along with the 15-150S support cover if needed. Together with the other side, these coils will equal to 13 pounds of support which should be the overall weight of the window sash.

Please review and let us know if you have any additional questions!
