Difference between 47-53 and a 54 Chevy

[48fordf1]

Hello,
New to the Chevies, but I do love these year trucks. Purchased a 52 Panel truck with a 54 front end. I assume the fenders are different between the two years, but wanted clarification. It has a 54 grill. I am purchasing a new Walker radiator for a 350 in it and I noticed Speedway motors sells one for 47-53 and a seperate one for 54. Can anyone tell me the difference in the two radiators. Seems the size may be diff., maybe diff. Radiator support. Thanks for any help.
