Grab the centerlink anywhere and attempt to rotate it to and from the rad. It should swivel freely thru several degrees, like maybe 5* or 7. If it doesn't it's probably bound up because like RRR says. Once you get it off you'll see a slight offset between the arm holes and the tierod holes.
The drop zone should be perpendicular to the floor. Yours appears to be swung rearwards.
Also, I seem to recall that the end that goes to the steering box is slightly longer from the pin to the tierod;not sure.
Did you by any chance, at the same time, have the idler arm out? While the link is off, just make sure it swivels freely; a tiny bit of resistance is normal. If it flops over it's either in need of grease or may be on it's last legs. Pull it down hard and wiggle it fore and aft, it shouldn't have any play in that direction,or at least extremely little.
