Here are the differences in the 3 stock radiators. Very easy to tell. You can also remove the radiator cap and look inside with a good light and count the tubes. A few may have the trans oil cooler in the way but I think you can still see over it.

2 core on the left, 3 core in the middle and 4 core on the right. The 2 core and 3 core use the same lower saddles and upper hold down brackets. 4 core saddles and brackets are different. The 2 core radiator is also narrower in width. that is why there are two sets of holes in the core support.
