Mitsubishi Galant Caliper Bolt Needed

Mitsubishi Galant 2.5l Saloon 2001 front caliper bolt needed, pictures below. Bolt is about 29mm long from the top of the head to the end and 20mm from the flange to the end of the thread.

It can be new or from a breaking car, any help is much appreciated as the car is currently languishing on an axle stand after the other bolt sheared off.
