Window tilt latch

A quick learner from West Dennis, MA says:
These have a patent marking of 5,139,291, and have the same measurements (as best as I can tell) to your Product Code: 26-391. Is that a safe bet? Or do you have another suggestion?

26-243 appear to be too fat...

Are there any others that I should order to try?
This is for our summer rental home and we need to get these fixed before the renters arrive in 12 days.

Thank you!

Tom from SWISCO responded:

I agree, your tilt latch is very flat. The 26-391 and 26-390 are your best options. To confirm, you'll want to review the dimensions we show on their store pages to ensure everything matches.
