engine stand bolts

[ju015dd]

I am picking up a 96 complete engine this Thursday and have a engine stand waiting for it at the house. What size are the bolts that I will need to mount it to the stand. Not sure if I will be getting bolts with the engine or not. Also, what size is the freeze plug I will need to fill fuel pump hole?
