balance P/N, weather strip & track cover help

Dear Window Expert,

I would like to order new channel balances for 2 non-tilting aluminum framed windows originally made by Western Products. The inside width of the vertical channel frame is ~15/16

Thanks Paul for your Reply, however recall from my original message that I said I was sending pictures of a 27C for REFERENCE ONLY, and that my needs are for replacement balances for my 27x42 and 27x30 windows whose weights are 24 & 22 pounds ... and your recommended 2730 option is only rated up to 19 pounds. Also, I realize that your S-350-28 matches my 27C unit, but I was asking IF THERE WERE BENEFITS to buying the S385-27, as I think I would like to have the top WITH WINGS, unless there is a reason NOT to have the wings. Re. weather strip for my sliding door, the old one APPEARS to be a soft "brush" with a 1/8" width spine with possibly an adhesive strip down its back and 1/4" width "top", but I provided the drawing of the groove in my door so that you could select something that will work with it. Looking forward to your continued help and recommendations.
