Hi Ken, thank you for posting,

I agree with the parts you have picked out as long as the dimensions match up to your originals. The Series 160 springs have a 1/2" thickness.

Alternate view of 15-199

These parts can be used for the left or right side of the window. Please let me know if you have any additional questions!
