Getting back to the other parts of my original questions, how do you adjust the horn button and spring mechanism on the steering wheel and is the slightly smaller spring that came with my ('55-57 Chevy) horn contact/bearing used on the 41-46 trucks in addition to the larger spring which goes under the horn button assembly? There are several things that can be adjusted such as how far down on the steering gear to set the steering column tube. That determines how much of the steering shaft sticks up above the steering wheel when you tighten down the nut that holds the steering wheel down which determines how far down you can press the horn button/collar assembly. Does everything just need to go on as far as it will go and it's all supposed to automatically work then (assuming the horn is good)?
