need some horn help

[kman67rsss]

i need to assemble my horn on a 67 camaro. i have it wired correctly(i think) with a painless harness. i need some help with how the button and associated parts goes together on the wheel. tha only diagram that i can find sucks. im not even sure if i have all the correct parts. if it would be helpful i can post a pic of what i have unless someone knows of a diagram online. thanks a bunch.
