If the tanks are still in good condition, and your current radiator is a 2 core, a good radiator shop should be able to punch an extra row in the tanks and install a 3-core center. The setup works well.
Just a thought, it cost me about $190 to have it done.
thanks guys the links are helpful. The local wrecking yard/radiator shop has 2 rows for 140 and 3 rows for 160 but radiator barn has 2 rows for 126 shipped. Im thinking that I need to get the 2 row because its starting to freeze here and I gotta fill half the tank everytime I start the truck so I kinda need something that will hold anti freeze asap and besides I can just do what yak said and upgrade it later.
