Yes, they can be fitted to any other Punto Evo. I know this because i went into my local fiat garage ordered my Gloss Black Front and Rear bumpers (which were surprisingly cheap for Fiat £50.27 +VAT for the rear, and £57.45 +VAT for the front) and then had them fitted within a day!
The only problem with it, is that the main part of the bumper (bit at the bottom is all gloss black) but the very top part; just beneath the badge is not. It's still looks really smart though so dont let me put you off.
Deffo worth it for the price though!
(I have to order another today because i hit a metal post the other day and cracked it!)
Hope this helped all!
