Vanguard double hasp mortise lock

Vangiard double hasp patio door lock

Only thing left on the door is the double hook inside the door. I pulled it out, the only markings are the vanguard name and a short note saying patent pending.

Facing the door from inside it slides open right to left. The holes measure 4" from center to center. 2" both directions to the large center hole. Broken arms that work the hooks unit is shot.

I can't find any set ups 4".changing over to something else is what I was thinking but can't find the same hole pattern. I watched your video replacing the handle etc but you used some of the old lock. Nothing left on this one needs new handles and guts. Should I just move to new spot on door and drill my own holes. Door is 1.5" thick
