The push button Panteras had aluminum Ford manifolds and 600 cfm Holley carburetors. The GTS Panteras had the list 4777 Holley carburetors. Your car apparently falls in between so I cannot say for sure if De Tomaso would have replaced the carburetor. Some of the other European owners need to chime-in and tell us what they've seen.
D2ZE is an engine part for 1972 mustangs. In Ford numbering the "D" stands for the decade of the 1970s, the "2" narrows it down to 1972.
If it were me I would install the Square bore cast iron manifold, casting number beginning D0AE and a Autolite 4300A "square bore" style carburetor. I can't believe a German inspector will know the difference between 1970/1971 factory parts and 1972 factory parts. The carburetors and manifolds all look the same. Once the car is inspected I'd remove the Autolite carburetor, place it on a shelf, and install a Holley carburetor to replace it.
Actually, I do realize how lucky I am. 
The picture below shows the carburetor mounting pad of the D3ZE intake manifold, with the big exhaust gas trench on the right hand side.
