Old Champion radiator leaks, Brand new Champion radiator leaks !

So my 6 or 7 year old Champion radiator developed a leak, somewhere in the core, hard to pinpoint exactly cause it was a slow leak.

Or I order up a brand new Champion radiator from Jegs. Shows up, looks great, polished aluminum not like the old one that was just bare aluminum.
They have changed the design for this application, mounting holes are more where they should be, but still not right. Still have to "slot" the mounting holes with a file. At least they moved the overflow nipple to the passenger side where it should be.
Spent a few hours over the last few days, making brackets, drilling and tapping holes, etc, to fit my electric fan onto the radiator. (new radiator has taller brackets on the sides, so had to change things around a bit). This also moves your fan, or shroud, closer to the engine by about 9/16".
So get it in, hook everything up, start filling the radiator, and immediately it's pissing antifreeze on the floor. It's leaking somewhere around where the core meets the bottom tank, on the drivers side.
If you watch the video, you can see it puddling on the bottom tank and running down the side.

So now I have to pull this piece of crap out and return it to Jegs.

Do I dare try another Champion? Is there a reasonably priced alternative?
