Ok I have an 04 1500 5.7L. I am going to have to change my radiator cause it is leaking. But my question is has anyone swapped out theirs from one that has the filler neck to the one without? I know you would have to replace the overflow tank to the one that has the pressure cap on it if you do, just didn't know if it is possible or if anyone has done it? I have seen some 04s with my setup and others with the other setup.
Thanks

 

Mine looks like the top one and want to know if you can change it to the bottom one
