Bell-Housing to Block, Bolt Size, (thread size)??

I bought a new/rebuilt engine today for my 91 YJ. 2.5l. I'm trying to get it on my engine stand but I can't find the size of the bolts (thread size) so I can bolt it up. A 1/2-13 doesn't seem to fit. Anyone know? is it 12mm?

thanks for any help.

Craig

Ok, For you that are using 7/16-14, I'd be carfull. the thread is actually 12X1.75 metric. I finally got a thread gage from work and the 12mm fit correctly. Or that is what my 94 yj 2.5 engine has.
