I did this type of individual car audio modifications in cars, but always on the basis of purchased additional "donor" and "recipient" cockpit elements - so that the customer, when changing the cockpit element, could always return to the factory version of the radio.
There is just always the risk that you will not predict something, something that will not turn out as expected.
You need a Chevrolet cockpit and a Dacia cockpit, some tools, lots of putty, paint or veneer to finish the surface and lots of time and patience ...
