93 Mack rd688s tri axle dump. I mainly haul 22 tons on regular ( dirt,asphalt,millings ) my current trunnion is cracked everywhere, and needs to be replaced. My question is, is the stengel bros. underneath mounted after market replacement trunnion stand durable enough to do what I need? And what is the best tool to use for enlarging the bolt holes for the new hardware.
