It's tough to tell what kind of balance you have without seeing the full assembly, but based on what I can see I think our best match might be the S140-10. Look it over and see what you think. If you have any doubts, or if you aren't sure, I'd be happy to investigate it further. I would just need a photo of the full assembly removed from the window. Alternate image for S140-10
