Mike, my oposite door only catches right in the middle. The door latch "tongue" catches on the striker plate in the center of the left door.
I'm gonna take a look at my photobucket and see what I can find and list it below. Maybe, just maybe it'll help.

This is my right door latch.

These are the "catches" that fit at the top and bottom of the left door. You can see they are labeled top and bottom.

All these photo's and more are on the photobucket link under my signature line. Take a peek if you like BUT I do NOT know if my AD is anything like your 46 doors. (I like your rear windows)

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
