you can get them from fiat, to get 2nd hand is next to impossible to get them straight again. but you could try them. i think i have my old ones kicking about osme where in good nick just took them off cos i had mine smothed out.
i had a **** load of body work done ( dont know if you have seen my car?) and the strips was in with the combined price so didnt get a itemised receipt. my bump strips which i took off was just black didnt have them sprayed. where are you from?
