Proper horn button installation??

[whitesswj]

I've never had a horn button in my 68 beofre. either i just ran a hot wire from a hot post to a button on the dash and then to the horn and HONK there you go or on the new 68 just use a scredriver and cross that little springy thing to the center and HONK.

I break down and buy a horn button from the jnk yard. 5.00 and all the stuff under the button

I got the button, little bowl looking thingy, the plastic ring, the 3 screws that hold that down and that little fierce looking disc that goes below that.

I put them in that order and a short keeps happening from the bowl to the nut that holds the wheel down. what's the missing factor here??

thanks sswj
