Hello. The parts are both 19 inches long. 1 part has " 1840 " stamped on it and the other part has " 1840R " stamped on it. Both are from the same window. Photos are included.
Assistance to identify parts would be appreciated!
Thank you.

Thanks for posting. See either our S380-19 or S385-19. The only difference between these two balances is the 'depth' of the bottom nylon shoe, or the 'heel-to-toe' measurement. See the diagram below for reference. Compare both with your old hardware to see what matches best. In either case for a stamp option choose 1840.
