The Calais Bumper is different to other models, in the sense that the Grill opening is bigger, and thus has a different grill to other models.
So to answer your question, the chrome strip will fit the bonnet no problems, but whether you can close the bonnet with a non calais grill is a different matter.
I do believe someone on here has fitted that Chrome strip to an SS Ute, if I'm thinking of the right car, but the grille itself was different (customised).
I might be getting my cars mixed up, but I'm pretty sure you can make it work.
Edit: I believe Dazzak75 has done it... Jump on youtube, some vids of his car
