Sliding Glass Door - Locking Mechanism

A quick learner from Payson, Arizona says:
We just purchased an older home constructed in the early 80's that has three sliding glass doors. The locking mechanism is broken on one and we would like to replace all three. Hopefully the attached pictures help. I found a mfg label that I can still read what looks like:

- Code 172-1
- Series 400-410-420-430

Your help is appreciated!

Hey, Ruben, thanks for getting in touch. Check out our 82-002 locking handle set and let me know if this would be a good match. It comes with a couple different hooks and mounting screws, in addition to a keeper. If you also need a key lock and pull handle, see our 82-302 and 88-002, respectively.
