Is the S395-2828" Series 395 Channel Balance option: 2740 the correct option for my window

Markings on the window are 27 4 DV CMC 8, length of item without header or foot is 28 inches, 1/2 inch non tilt window channel balances with both shoes. My broken window has a plantation shutter so I could not remove it easily. I took out a smaller window instead to take pictures of the old channel balance with its header and footer and pulley claw. The old windows are Fisher aluminum single hung double paned windows and I am assuming those components will be identical across the various window sizes...

Thank you so much for reviewing my information. The bottom fitting on my old channel balance is 1 - 1/8" so I will go ahead and order the parts. Thanks again for your help.
