Bellhousing to Block bolt type/size

Ok gents,
In all my wonderfully great common sense, I went and pulled a 4.0 out of a grand cherokee today to rebuild to replace my aging 4.0 in my yj... and like the idiot I truly am, I left the transmission to block mounting bolts (bellhousing to back of block) at the junkyard... I have no idea what thread pitch or anything they are, and I need to find out so I can put the engine on my motor stand tomorrow... If anyone can PLEASE help me out here, I would be forever in your debt!
Thanks

Sometimes you cant win for losing... The XJ yesterday crudded out both the optima battery, the lower rad hose and the radiator itself.... Then the YJ started blowing smoke (ring on number 3 cylinder started to finally let loose) and now I pull a bone headed move like this...

IIRC, they are 12MM X 1.25 pitch.

I just did a 2.5L motor job & used 100MM length bolts for the motor stand.

When you're done on the motor stand, chop the bolt heads off & cut a slit in the end (to use a screwdriver in) and use them for line-up pins while reinstalling the motor.

There is no situation that cannot be improved with a small but well-placed explosive.

Max you are the man, hopefully I can get this motor on the stand today and actually start tearing into it. Expect a picture/buildup thread in the near future when I get further into it.

Looking forward to seeing your project!

Please take some detailed pics & pertinent info notes for the rest of us to learn from!

Max, 12mmx1,25 were too big wouldnt even fit in the holes for the mounts. Im not sure if the 4.0 used the same bolt holes as the 2.5L but thanks for the help just the same!
