5.3 swap 96 Sierra which radiator??

Swapped a 5.3 into my 1996 Sierra need a radiator old one is gone lost in the swap. So which radiator works the old 96 or one from a newer year?? 2000ish radiator easier to come by my concern is will it fit. Anyone else here done this swap let me know.

You can use the one from a 96. I used my original 90 radiator and it works fine.
