Basement door latch replacement - 2004 Crescendo

[GreenAcresMO]

I have several of the door latches that are broken. I found a thread that mentioned SouthCo C5-23-45 as the replacement part but when I search on it, I get something that is very different...

I am also have some of the "hook" or "loop" that the door latch secures to that are broken... (water intrusion and rusted... ).

Any help in securing these would be greatly helpful.

Thank you,

KJ
