Default Need bolt size for exhaust

I need a bolt for the exhaust on my TA, the bolt fell off on the way to work
and i am afraid to move the car and knock off the tip that is hanging dangerously close to the ground

The bolt in question is the one that is used to hold the hanger on the drivers side of the car for the muffler, there are 2



think it is #18 or #15 in this diagram

need to know the GM part number or what the bolt is
thanks

The bolts for the drivers side exhaust hanger are M8x2.12x30 part number 11504765. I think there are the same bolts on the passenger side.
