I was thinking ( bad for me ) did the duel cab split have a pannel van rear ( cab ) section on it .?? can I get a two door and fit a rear cab to make a duel cab ?? seagull

From my observation, not even close (although you might like to research some of the information about the Binz, which didn't come to australia).

Have a look at any of the posts about "Leo's" restoration and you'll see how different the profile is.
