Crooked K-Member

Perhaps, your car was in a pretty major front end accident at some time. I am no expert on this, but I suggest taking it to a frame straightening shop. If you don't want to do that, or can't afford to do that I suggest using the water pump fan hub and the oem radiator and oem shroud to line up the frame horns and k-frame, by pulling the frame around to center the hub in the shroud fan opening, accordingly.
the reason I suggest centering the body/ frame around the fan hub, is because I bought a 74 duster360 from my brother in law who piled it into parked car while drunk. When I hung new sheet metal on it and put a new rad and shroud in it, it interfered with the fan by about an inch on the right side, which meant the front end had been displaced to the left by at least that amount.
