I've had some of these made up from 18swg mild steel. They're plasma cut and hand-folded, made using a template taken from a Firenza (thanks, Fred!). In order to allow for measuring inaccuracy, I've had the main "holes" for the headlamps and adjusters cut slightly oversize, and I haven't drilled the holes where the headlamp plates screw into place, so you can align them on the car and mark them to suit. They don't have the lower bracket to mount the grille, you'll need to add that, and the part that sticks out for the screw on the inner nearside headlamp is a bit larger, again to allow proper alignment. You might want to trim it back once you know where the screw hole goes.
Selling for £70 per pair excluding P&P, please message me on here or email to mike@firenza.net if you are interested.
