I have what I believe is a truely one of a kind AMT 1968 Plymouth Roadrunner.
I had recently bought this kit off of E-Bay and it was still factory sealed.
What makes this kit one of a kind you may ask? 
It came with a body of a 1969 Plymouth GTX.
I didn't notice this until I had it pretty much all done and was about to install the taillights. I looked at the provided tailights and thought, there is no way these are going to fit the body. I then checked out the box top and noticed the car pictured had round side marker lights on the body, but the body I had came with rectangular side marker lights. I jumped online to look at images of 1968 and 1969 Plymouth Roadrunners and saw the same differences. I then checked our Round2, AMT's new parent company and they had instructions for a 1969 Plymouth GTX and sure enough, it has taillight bezels and red clear taillights. Mine didn't have bezels and they taillights were chromed and had to be painted red.
Sorry for the long rant, but all in all it turned out good, except it's lacking taillights.
Btw, my claim is a shot at AMT, who can't get the right body of a model into a box.
