Spring Damper & Shoes Question

Dear Customer Service Rep:
I need to order Qty (2) Item Number S600-26 Spring Dampers to replace 2 that are no longer functional in my windows. I am thinking that the existing shoes that retains each spring damper are probably ok but I feel I need to order replacements just in case they are needed. But, looking at the choices on your website I cannot see one that looks like the ones installed in my window.

2 pictures are attached. Can you help me to determine which Shoes I need to order?

Thanks,
Walt

Thanks for responding Tom. As it turns out I was able to repair the spring damper and reuse it. The shoes were ok to reuse as well. I adjusted both dampers on each side of the window and the window stays up now as it should.

Thanks for responding though!
