I recently bought a 280z with a great rebuilt engine. The only problem is that the front end has been wrecked. I love the car, but I don't like the large bumpers. I was wandering how hard it would be to replace the front end with the classic 240z look, with the signals in the lower valence, old grille, and smaller bumpers on the front and back. How hard is this to do, and is it possible?
