Window tilt latch

A quick learner from Glen Allen, VA says:
No numbers or markings found on our existing hardware. I'm wondering if 26-419 & 26-420 will work? The main difference I see is the tab on our latch is 1/8" back and not 3/8" like the one shown in the additional images. As you can see from my pics, our existing latch has very small tabs on the side that make it easy to snap in. Do you have anything similar or know where we can find a replacement?
Thanks for your time!

Hello! Thanks for reaching out to us. We unfortunately don't sell a latch with a 1/8" bottom tab backset. However, if all the dimensions for the 26-419 and 26-420 match up except for that bottom tab, then I think they will still work. That tab does help these latches snap into place once installed but they are not strictly speaking necessary. The latch will mostly be held in place by pressure from the jamb itself after they're installed. They won't be loose or anything.
