Preliminary assembly of the Planearound door latch system, which includes a mechanism integrated in the original mechanism.
I created the necessary holes where indicated in the instruction. On each door i drilled the hole to accomodate the middle latch mechanism and the other holes to allow proper operations.
The final adjustment of the openings has been done when inserting the door pins and the rack. I think there are a couple of places where the Planearound instruction are not correct. In one case the hole to facilitate the insertion of a pin on lower door handle rack is misplaced.
