The hard bit is:-You will need to drill a hole down the centre of the broken bolt, when you have drilled about 2cm use a stud extract to ease out the broken bolt. Stud extractors are relatively cheap they are a tapered left hand thread which grips the side of the hole as you try and unscrew it. If you put a drop of brake fluid round the broken bolt and let it soak in, it acts as a penetrating agent. Take the drilling easy don't force it!
