Help with replacement baby cradle hardware

Hi Folks,
Looking for some help with locating a supplier for some baby cradle hardware.
Got my 1st bub due in about 6 weeks and I've brought down from the loft the baby cradle my dear mum looked after for the 40 odd years since it was used for me. My wife and I thought it would be nice to have our baby in the cradle that I was in all those years ago.

I have gone to assemble it only to find some of the hardware is missing. Some of these parts can be replaced at my local hardware store. But I am missing a pair of vital hooks. These are the hooks which support the swinging cradle in the stand. The hook shafts have metal threads and have 2 nuts which can be adjusted to obtain the right distance for the hook to protrude from the stand. The hole in the stand for the hook shaft is 6mm in diameter (but in need this can easily be changed to suit a replacement hook).

Have a look at the photo in the link below.

Got and tips on where I can find this hook? I've found a place in the US (http://ift.tt/1LEPJlZ) but I'd prefer to buy local.

Thanks for your help
