Rite, that link that jay posted, you replace that part that u have snapped with a m5 threaded bolt right, then you cut a slot in the head of the bolt to make the pronged bit like the part in your picture. Works a treat and is alot stronger than the actual part your holding in your hand. Just visualise the part in your hand with the threaded end still atatched, then visualise it as the bolt your gonna make, jobs a goodun
