Tilt aluminum window latches (plastic)

I need to order 7 sets (R and L pairs) of these window latches on very old tilt aluminum windows with screens. The body length is about 2 and 5/16 inch, width is about 23/32", length from inside to center of hole is about 1.75" and the tongue insert measures about 1 and 11/16" and protrudes about 3/8". It appears that the Keller tilt window latch #26-089BP is the closet fit. Please advise.
