Thanks for posting! 1-13/16" is an odd size for screw hole spacing. Are you sure that's accurate? If so, could we see some pictures of your tilt latches? That would be a big help in our search for a replacement.
Thank you for the images! That helps clears things up, though it's a bit difficult to be sure with a damaged latch. Now that I look at it, though, I think it might be corner type tilt latch. Could I see one that is undamaged?
Same problem here.
If it worked I'd like to order a couple...
