Thanks for help. I read from Wikipedia, there is actually 3 main models, P400, P400S and P400SV. NightEye has right:

The SV can be distinguished from its predecessors from its lack of "eyelashes" around the headlights, wider rear fenders to accommodate the new 9-inch wide rear wheels...

so I have to make those grills 'cos SV were from 1971.

Here is link for P400 image.

BTW Tom has right about name (Veloce - in Italian mean fast, Volante - steering wheel )
