Hi Everyone, my wife's Fiat 500 1.2 petrol convertable has started to leak gearbox oil from the end casing on the gearbox. The casing seems to be rusting on the outside and starting to perforate, probably due to the close proximity to the nearside wheel and the debis that would throw up. . I cannot seem to find a new casing or a second hand replacement and I wondered if anyone has had this problem before and how they resolved it. Ideally if someone has a Fiat part number or knows where to source one that would be great. Thanks, Peter
