[Roadsters] OT: Rear 1/4 window latches

[O'Farrell, Fergus P (AS)]

I am helping a friend replace the < windows in his Ford Capri ('member these?)
and it seems the < window latches are press-fit onto the glass (for security,
so you can't just unsrew the latch from the outside).
I am looking for a pair of latches for pop-out windows, similar to later model
Ford Ranger or S-10s (or Nissan Hardbody for that matter) king cab rear
windows.

All of the online used car part places want to sell you an entire < window
assembly, which is a waste when that glass is just going to be thrown out
anyway.

Any j/y resources, or anyone got some other alternates (B210, Sentra?) to
suggest?

Thanks for the info,
FergusO
