Sliding Door Lock

Looking to replace this part, sliding door single hook lock.

Gladiator Glass is on the Sliding Glass Door.

Lumberyard Suppliers & Builders Pride are on the inside of the door.

Any help appreciated!

While you are at it, see if your mortise lock can work upside down. Most of those are meant to lock up, not down. If it can't be reversed, I would recommend adding a screw or block in the header to prevent lifting the lock over the strike. There may already be something for that purpose. Check for safety.
