Radiators, New smaller one in Stage 2 kit?

[Mastertech5]

Anyone know if there is a difference between the radiators that came with the Stage 1 kit and the ones that now come with the Stage 2 kit or possibly the ones for the deluxe nose or truck. The one I got with my Stage 2 kit has a flat bottom tank that does not look like the one in the assembly manual that has a rounded larger bottom tank. It may be for the deluxe nose but I haven't seen one to know. It's at least 4 inches shorter than what the manual shows and there is no radiator filler for a cap. And no trans cooler.
