M122 elbow bolt size

[XXWildCoyoteXX]

Bit of a pain trying to find this out, but i am in need of finding out the bold sizes for the elbow to m122 unit. Sadly did not receive the bolts when i purchased the unit.

Any input would be great. Currently have access to a bolt selection at my work so sooner the better with sizes would be a plus.
thanks
