I actually used the radiator support from a 1.5 ton for my 1/2 ton. The support itself was the same dimensions. I did have to convert the bottom from the one to the two supports and weld new triangle supports on. I bolted them on, got the whole front sheet metal lined up then welded the brackets exactly where I needed them. In other words I’m not sure they are going to be in the exact same location on every truck. If you need to move them, it’s not the end of the world.
