Ok found one

It would seem i had one still bolted to the side of a spare block
Anyway thought i would post pics of my fix for the bracket bushes..
Went down to pedders and the staff were very helpfull they measured up the old bush with some callipers and came up with some that fit perfect

Pedders suspension for your alternator anyone? haha
They were quite steep being $29.00 for the pair but im happy knowing i shouldnt have any problems.
All you have to do is cut the lip off one side of the bush with a knife, They told me not to use a bench grinder because the heat can make it fail?? Use a bit of the supplied grease on the outside of the bush and it will slip into the bracket with ease!
