One of the screws on the fuse box cover (the one in the dash) on a 2013 Ducato is damaged (looks like it's been cross-threaded). I assume that the only place to get one is Fiat (and likely that I'll need a captive nut - not sure if that may have been damaged). Does anyone have part numbers that I can ask Fiat for? I'd pop in, but there is not a Fiat Professional centre close to me.
