Thanks for the reply.
Sorry, forgot to mention I'm located in Australia. So I can't check out your local hardware stores.
As there seem to be some non standard screws I was hoping someone did a comprehensive kit
instead of me replacing the wrong screws with new wrong screws.
I saw the E-Bay listing but again this is only for one size screw.
I'll just have to go to the local store with a pocket full of old screws and see what they have.
Thanks,
Mal.
