Interlock and plate for 82-081

Question

I recently ordered the set 82-081 to replace my existing patio door lock and handle. Can you tell me what interlock and plate I need to purchase to complete it? I didn't have an exterior lock with key and that's why I bought it to have a key lock on the outside.

I'm not sure if the 82-081 was right for your door. This is only compatible with a couple different mortise locks, but none of them match the cutout I see in your photo. Do you have the original handle set on hand for me to see? Can you also tell me the distance between the two installation hole centers for the mortise? I'd also like to know the overall width and height of the oval hole.
