Thanks for posting. If the metal channel is indeed 28" long, then see our S770-28. If your window sash definitely weighs between 34 and 36 lbs, the stamp option 28F should work for you, but I advise double-checking the sash weight to get as precise a measurement as possible to be certain. If you need to replace the pivot shoe also, see our 15-178. Compare with your old shoe to confirm it's a match.
