Maybe I have them in the wrong holes. I got two holes on the passenger side. There is a threaded hole next to a non threaded hole. The prong on the horn bracket seems to fit in the non threaded hole and the bolt is the same threads as the threaded hole. Does anyone have a picture of where they mount. Also is the windshield washer bottle the same on a 71 chally as a 70. Or is the 71 different from all the other years.
