The pieces on the top are from one window. The metal bar on the bottom is from a different window.

The smaller part on the top has a pat. no. 5.704..165.
They are from windows that were install in 2003/4.

Thanks for your post. Starting with your pivot shoe, have a look at our 15-199. This part can be used with both the Series 160 and Series 165 coil springs. You will need to measure the width of your spring to determine which of the two is the better match. There should also be some sort of stamping or marking on the spring to determine the spring strength. As for your pivot bar, our 26-378 is worth considering. Review all the parts mentioned and let us know what you think.
