Looking for Replacement Vinyl Window Latch

A home owner from Colorado says:
Hello! I have one window in my home that doesn't have a full latch installed (and maybe never did). Based on the photos/measurements of a complete window latch (another window in my home, also Jeld-Wen), I was hoping you could point me to the correct kind of lock?

I was thinking this looked close:

But the interior of the keeper looked a bit different (since all I have on the window in question is the keeper). It's also unclear what the keeper measurements are to know for sure?

Would appreciate any pointers you can provide!

Hello,

Your lock reminds me of the 90-278 but you'll need to compare the dimensions listed below, especially the 2-1/16" installation holes, to yours. Thanks for posting!
