Ford A/C :: 4ltr - Radiator Started Leaking From The Seam Close To Where Bottom Hose Is

This is strange, Had the truck for about 3000mi bought it at 147k now has 150... Any way it runs great but the radiator started leaking from the seam close to where the bottom hose is. I have since changed the radiator about a week ago 500mi a week work truck.

Now it seems to be leaking from the very same area, what I mean is the area around the hose is dry but just up the seam a bit it barely leaks, and mainly after the truck cools off at night. These radiators seem extremely low quality, is there a substitute higher quality.

Also of note mine is the 1" core, I was told there are others but they will not fit, I must agree it seems nothing else would fit due to space constraints. These radiators just kinda sit in a cradle and aren't really under any stress that I can tell so it doesn't seem as though that would be the cause.

Also of note the shop where I bought the new one took it out of the sealed box and tank pressure tested it as they do for all new sales, no leaks, I have not pulled it back out yet cause I would like to get some thing less flimsy if it exists.
