Sunroom balance channels

Question

The balance channels in our sunroom windows are toast. They're half-in deep and 29 inches in length and have "2840S" stamped into them. Each window had one per side, from what I can tell, but they've all fallen out. I was hoping you stocked a compatible replacement.

I am confident we can replace this channel balance, but I do need to see a version that has the nylon fittings intact. Is there an identical window in the house from which you could remove the balances and show us the fittings on each end? From there I'll so my best to assist.
