Sourcing CV joint bolts in Victoria

[gibrate1]

One of the bolts holding the front cv (on the front shaft) onto the flange was rounded off. Does anybody know places where I can source a replacement bolt?
M8 x 1.25 60mm long
bolt head same size as the thread (removable by 6 point socket)

I'd be checking at a local wreckers (self serve) to see what's available.
These guys may have some but are probably a bit far from your LOC:

Thanks, TR Laredo for the head up. Ended up sourcing a replacement galvanised high-tensile bolt with a Allen hex head.

I was going to suggest a Gr12 Unbrako, but looks like you have the next best thing. I would recommend changing all the bolts to keep them the same for balance.

Edit...
I've used quite a few socket heads where hex heads have been damaged - particularly on the gearbox crossmember and the transfer case bash plate.

Thanks, JeanLuke for the suggestion of a replacement Gr12 Unbrako bolts. Are those available online? Anyways, the replacement bolt weighs roughly the same as the factory bolt. I reckon Dirt and debris will contribute more to an imbalance that the weight of the replacement bolt.

They're all over eBay and Amazon. Unbrako brand is Gr12.9 by default.

Edit:
Dirt tends to spin off a CV joint. A bolt of different mass hopefully won't. At highway speeds the driveshaft is spinning at around 3000rpm. It doesn't take much to make it vibrate.
Edit edit:
At least change the opposite bolt to keep them the same.

Fine, I replace all 6 bolts with new socket head ones! They cost $1 each at my local Auto one parts store.
Factory:22 grams
New socket head:28 grams
