The parts catalog lists them as different part numbers, so I would say no. I wouldn't install a used radiator anyway if you plan on keeping the truck. For around $100-150 you can get a new OE replacement.
If your going to change radiators why would you use a 16 year old part Buy a new radiator and you won't need to do the job over again in 6 months Try rock auto for your parts their usually 1/2 price than chain auto parts stores
