Heyhooo, has anyone got any of those?? Or knows where to buy them preferably in Australia?? thanks heaps. ??????

The other option is to cut off the broken bit and drill a hole (as shown below in red) then glue in a stainless cotter pin

Thanks everyone, thought the pictured kit is neater than the cotter pin, but guess it's a much quicker and easier fix..
Happy days..
