I have a 1989 Hatch that has been missing the rear window latch for some time now. Well, not missing, but broken.

Piece 18-21 here


It says discontinued on this particular website. Anyone have any advice on where to source one from? Aside from the junkyard. And how exactly do you replace them? If there is a fix that removes the opening feature, I'd be okay with that for the time being. Mine is cracked where it rotates. I just want the window to stay shut. When I shut my front doors, the compression of interior air smacks it open. It's just sort of embarrassing.

Thanks
