Need window channel balance and top sash guide

28", please.

Top sash guide measurements:

-width- 5/8"

-height- 1 15/16"

-depth of top section- 5/8" (not including overhang of top flat portion)

-depth of bottom section- 3/8"

-screw hole (from top) 3/4"

-ledge that catches channel balance at bottom of top section (from top)- 1"

Would 18-065 work for us, even though the ledge to catch the channel balance is at the top, instead of 1" down from the top?

Thanks!
