Ok im hoping some of you guys can help me out. I need to know what kind of mounting surface is on the athearn RTR 4 axle trucks used on the GP's? Im slowly, very slowly working on a custom project that uses a SD40 frame with milled fuel tank. The frame accepts the sd40-2 trucks that have that circular portion and flat metal over the gears. Do any of the GP bloomberg trucks use this? Can anyone post pics?
