Hey Niko, nice work but that's not the wiper motor. That's a roadrunner "beep beep" horn that is left over from another kit that the sprues were originally made for. The instructions wrongly tell you to put it there. The real wiper motor is a small chrome piece that is between the shocks and air cleaner on the sprue. I have seen many, many AMT Mopars built with this mistake.
