Purpose of Mystery Factory Hole in Radiator Support?
Why is this factory hole with a nut welded to the backside on the radiator support?
It is only on the passenger side.
The attached picture is a 1972 Blazer from the Internet, but my 1972 GMC pickup has it and I'm trying to figure out why GM put it there.
