Anyone know the PCD for the Wilwood Quick Release?

It says on the Wilwood site "Standard 3 bolt pattern"

Unfortunately I can't find out what this 'Standard' pattern is!

Thanks

I have one in the garage, can you wait until tomorrow evening for me to measure it? If it helps in the meantime, a kart 3 bolt pattern wheel went on with just a little opening up of the holes

Cheers
