Make sure the window sweeps are in decent shape before you buy those pieces. No one makes replacements for these. Ask me how I know.

Fortunately, the window sweeps are still in decent shape, just the main pieces themselves are so brittle that when I dropped one it shattered like glass.
I should’ve reinforced them with fiberglass, or something similar. But hindsight is 20/20.
