Got my fiat 124 m/c on and i'm making up the copper brake pipes but the unions MK put on are meant for a sierra m/c. Does anyone know what thread unions i need to get to replace the metric ones?

Fiat have always been metric but Ford metric fittings are a a coarser pitch than most european manufacturers used.

Just been told they are m10 x 1.25 (thanks whitestu). Sierra m/c seem to be m10 x 1.00.
