Crimping a radiator side tank

The radiator for my 01 Durango was cheap enough I replaced it. That's what they all do. You can try to recrimp the thing but I suspect it will lose the squish shortly and then you have to pull it out again. That makes me say words that makes my wife put dish soap in my mouth while I sleep.
I replaced the radiator in my 02 quadcab, (about the only thing I had to do in 15 yrs.) , the new one started leaking in the same place as the orig., I made a bolt together clamp to pull the pieces together and hold them, was still on the truck when I traded it off.
