I DONT mean the abarth, just the standard 1.4 16valve, every thing i have read says they are so similar and there are allot more after market options for the 500 compared to the Panda.
Like that thread I linked said. It will not be in the same position and you'll have to other re-welded or cut bumper to one side. Other that than it should be same fit. Just the bumper outlet position is not gonna mach with pandas.
