I need to repair or replace the quarter vent latches on my Ek. The problem is they both dont latch at all at the moment, so effectively I cant lock the car

I've done a search and can't find much info on the latches themselves, was mostly to do with rubbers for the quarter vents

Am I able to get some second hand or repro latches and fit them? Or do i need to replace the entire quarter window frame? And no I dont want to single piece windows
On the drivers side theres a stub
On the passenger side the stub is broken off
