Replacement window sash adjuster

A handy person from 06786 Connecticut says:
I need to replace my window sash adjuster. Left and right sides show same numbers D10 7#27 5 80 AND 11600-2 on them.
Right and left side dimensions are 3" wide x 6 1/4"+ 1/2" long x 3/4" thick.

Please see attached picture.

window dimension is 40"x 19"

Please let me know the replacement part numbers.

Thank you for your help.

Based on your stamp of "7#27," I recommend our 24-737 Andersen operator.
