Changed the radiator, then reassembled it. A process that took 8 hours in its entirety and involved a wrench to my face. The radiator truly only took around 4 hours to swap, the hard part came in getting the damned thermostat housing to not leak. If anyone runs into a situation where the bottom bolt feels like its bottoming out, or you have any kind of a concern about the aluminum housing being compressed or whatever. Stick a couple of washers on each bolt, its what finally worked on the 3rd gasket.
The old radiator was gone, I had been having overheating problems and after getting the old radiator out I'm kinda glad I don't have a functioning temp gauge. The head warped after it boiled over on the po, so I'm glad I got rid of the likely cause of the boil over. (Rebuilt engine with 10k miles since rebuild, radiator ought to last at least 4-5 years since the original mopar is what I replaced.)
Also got the thermostat and the hoses while I was at it, they were all replaced 10k miles ago but since I was replacing the radiator I got the parts to replace them as well.
If a week goes by without needing to replace something, pinch me because I must be dreaming.
