I bought a NOS fender for a 73 camaro for 20 bucks once. I got it home and was all excited to put it on, I get it on the car and bolt it down and the whole fender was about 5 inches too far forward but all the bolt holes lined up just fine! Turns out that the factory messed up and were one spot weld off center so I just drilled out the spot welds, moved it back, rewelded it and was done with it.
