stuff like this is why i have resorted to only installing radiators from local shops. i can inspect before leaving the store/dealer. i’ve had very good luck with carquest/acdelco’s from the dealer with only 1 out of atleast 20 having an issue. the threads for the oil cooler were stripped and blew the fitting out upon start up.
I bought a acd gmt400 bbc rad from uhaul years ago it came damaged but serviceable- but I paid for an undamaged unit, they sent out another, I still have the first one on the shelf.
I bought a Spectra Premium CU2938 Complete Radiator from Amazon warehouse a few years ago for $14.55. It came slightly bent length-wise but looks usable. Still sits in the garage.
I can't find the after picture, but I was able to straightened this radiator out to where you wouldn't be able to tell it was bent unless you closely examined it.
