My 20-year old American Craftsman windows have sash pivot bars that look almost identical to your part # 26-400
Alas, the measurements a just different enough that your part will not do.
- My part has stamped (1054)
- overall length 2 1/2" (as opposed to 2 5/16")
- space between holes in 3/4" (as opposed to 1")
- distance from hole closer to pivot (sash) end of pivot bar is 1 7/16" (as opposed to (1 1/16")
- Width of bar is 5/16 (same as your part)
- size of "ear/tabs" is 5/16" (as opposed to your 3/16")
