I know that I posted another Dalat before, but I think they are different enough to stay as two puzzles.
As there were a number of quite different Dalat body styles and models, personally I would say don't merge them, but I appreciate that this is not my call... 
I strongly agree.
Here are some of the descriptors Citroen used to distinguish the various La Dalat body styles:
Pick-up (this puzzle)
2 doors + rear gate, folding rear bench seat, fully removable canvas top, no side windows
Limousine (
your previous puzzle)
4 doors + rear gate, folding rear bench seat, enclosed body with solid metal roof, sliding windows on all 4 doors and rear panels
Break 3 Portes2 doors + rear gate, folding rear bench seat, enclosed body with removable roof panel, sliding windows on front doors, fixed rear side windows
Break Commercial2 doors + rear gate, folding rear bench seat optional, enclosed body with solid metal roof, sliding windows on front doors, solid metal rear panels
For clarity, I've added the desciptors to each of the thread titles.
