Default Anyone know bolt size for bellhousing bolts?

I'm picking up a spare 1uz for my 400 and need to know the correct size bolt to get so I can mount it to my engine stand.

Anyone got one handy and a thread measuring tool or anything?

That was it Jake, and for reference if anyone is searching in the future, I used M12x1.25 fine pitch, not standard pitch. I have a heavier duty engine stand with a right at 3" arm on it that the bolt needs to pass through, so a 3.75-4" length bolt is what you'd need. Probably less for a cheaper engine stand that only holds about 750lbs where the arm the bolt passes through isn't quite as long.
