K-member at the end of its life?

I see no one mentioned that 340 cars had these pins reinforced with large crescent- shaped pieces, welded on. Then a washer was welded front and center making them easy to identify,when installed, by just bending over and looking for the washer..
I must really be getting old, cuz my naked K felt more like 350# back in 98.Well not really 350, but I guess I'm not as strong as I once was.
