Original Generator Bracket Bolts?

[hursst]

Hello,
  Does anyone know if the original generator bracket nuts and bolts on a 30 U were hexagonal or square?  This is the bracket that goes under the generator has has two attachment points, not the bracket on top where you can adjust the tension of the generator belt.  Thanks!

Just went and checked my 30-U, they are hexagonal, looks to me like 1/2”? Included a pic of the cab side of the generator.
