Approx. 20 yr old BF Rich window, 28"x ~48". can't find similar parts on website. The measured depth is 1/2", width 1-1/4". I think it say 6 pounds (maybe 9 if reading upside down), but 6 lbs seem right for size of window??

Thanks for replying. I have one other question. Besides the pivot shoe and coil balance, isn't there another piece the coil attached to and is mounted with a screw half way up the window channel (shown to the right of the photo)?
