If the flywheel was machined all the way across including the area that the pressure plate bolts to ,it won't affect clutch action the way you describe.
You say the truck won't move ,clutch disengaged all the time, don't have the disc in backwards?The truck has a hydraulic clutch?An external slave cylinder or the internal type like on Jeeps?And you're absolutley sure the plate and disc match the parts you removed? Gotta be the bearing then I guess.
