Need bolt size for exhaust
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
Which no gm dealer in town had no hardware store has
Soooooooooooo I limped home and drilled the hole out and tapped rethreading both sides to a 7/16
