This is the POS radiator. In person you see how shoddily made it is. I expected that but want to get the truck back on the road asap. The mounting bolt flange that is causing issue is one of the bottom upside down U's. One of them is not deep enough, so radiator won't sit down low enough for top bolt to line up. It's only by maybe 1/16th of an inch, but just enough to keep bolt from line up just right. So I'm going to have to file it down. Again, just shoddy craftsmanship.
