Shackle pin diameter

I've searched everywhere but can't find a definite answer. I'm making some extended shackles to suit Bruce's poly bushes, but not sure what diameter to drill the holes? I think the original pins are 13mm but i'm guessing 1/2" would be easier to but high tensile bolts for? I know there's not much of a difference between 12mm, 1/2" and 13mm but i just want to make the best choice.
cheers

Use 1/2" bolts.
1/2" 12.7mm - it's the best fit. 13mm isn't commercially available.

I knew someone would say that, seeing as i've only got 12 and 13mm drill bits.
Off to the shops i go

But if you're going to do that remember to only drill one side of the plate at 10mm and the other 13mm or the shackle will be really sloppy.
I really hate those stock pins. I have a range here in the shed with horrible wear on the 10mm threaded bit

Done and done, i love my new drill press
For future reference my shackles are 50x8mm plate, 170mm total length, 120mm hole to hole.
