Broken plastic finger latches on storm windiws

A home owner from New Jersey says:
I guess I bought some cheap storm windows at home depot 5+ years ago and all the plastic latches are now broken (except for the screens). They look like some "Weatherstar" windows I've seen online and the guy at home depot said Larson bought "Weatherstar". All the Larson windows now at HD have metal latches, but they look to be the same size and the cutouts on the side rails appear to be identical to my windows.

Based on the attached photo, can you tell if Larson parts will work or do you need better specs?
Thanks very much

For this type of latch, we have recommended our 91-010 and 91-011. They are metal, but I believe the dimensions match. Just compare them to be sure.
