After just 7 months and 4451 miles my differential has gone bang and therefore need a new gearbox, it is the 1.4 litre 16 valve multi-air engine with the 6 speed gearbox, fiat are doing everything they can to blame me so that they don't have to pay out for it on warranty, has this happened to anybody else? And does anybody know a fiat only breakers yard that might have a new punto

Would the 6 speed gearbox from the grande punto fit also?
