NIS15L, all the utes 1971-1977 had the metal grille. Just get all the pieces you need, and then you probably have to modify the mounting brackets on the front of the body.
Stirlingmac, how right you are about the headlight surrounds, something I did not notice until recently. A lot of coupes have silver ones, I wonder if they have aftermarket replacement grilles -- some new grilles seem to be all black and others all silver.
