springs broken on both side of window

Dear Sir/Madam,

Our window is hard to be left also will not stay at left position. After took the sash off and found springs on both side are damaged, each side has two pieces of springs. I can only find "MEGA 6.5 33""makings on one piece of the spring and can not found anything else. The sash size is about 29"high and 37.5" wide and weighted about 20 lb. Is there any replacement for those parts?

Thank you very much!
Tina

Thank you very much Casey! I am glad I finally found the right place to get those parts. I also found plastic door guide replacement on the bottom of shower glass door.

I just have one more question about the S160 Coil Springs. Will it be easier to use one S160-10 instead of S160-4 and S160-5?

Thanks again,
Tina
