Hi Mate,
Ive got some badges on my grande sporting, one metal badge on the front grill in the italian flag colours and two small rubber ones below the side indicators on the wings, all these were brought off e-bay they add a nice touch. Try abarthbadges.co.uk, thats where i got mine from he also sells the badges on e-bay !. Hope this helps. Also they are all self adhesive
Cheers Darren.
