Help replacing a loose patio glass door handle set

My patio door lock hook does not stick out to engage, because I guess it is too loose. I need to purchase a replacement. Essentially just the metal part in the center piece would be fine. Here is what it etched on the door:

PPG Herculite tempered glass

6CFR1201 CII

ANSI Z-97. 1-1984

SGCC-296 IGH2397

For future reference, that handle most likely belongs to an "International" brand door. It probably says so on top of the handle. Yes, 82-218 should work.
