Window latch dimensions

A home owner says:
I bought some replacement latches but the part that retracts is too short to extend into the frame. The old latch shown on the left is 3 1/8 x 1 3/8. Please give me the dimensions of the length of the part that retracts so I can be sure it will work.

The section that extends is 1/2"

The existing holes on center are 2 1/8"

I'm trying to avoid having to redrill holes in the window frame to fit replacement latches.

Thanks.Appreciate the help.

Thank you for posting. How about our 26-120 & 26-121? Could these be possible replacements? Take a look and see what you think.
