Lock parts for Andersen PermaGlide door.

A home owner from Tuckerton, NJ says:
I am need of a new mortise assembly?, the part installed in the door, (pictures 1, 2, &3) for an Andersen PermaGlide door. The numbers visible on the assembly are: 2573558 right below the Andersen logo, and 7700-14 further down. The part measures 4-1/2" long, 5/8" thick, and 1-5/8" deep.

I should also replace the striker? assembly (the part installed in the door jamb)I have been unable to get this part out in order to find a number. But the in-door piece is what I need most.

Ah, I recognize this. Unfortunately, the original 2573558 Andersen lock has been discontinued. We recommend that you use our 82-037, Andersen mortise lock, as a substitute.
