Turn Signal Switch

[backinblack]

A couple weeks ago, I changed the turn signal cam, and now discovered that the reason my horn doesn't work is that somehow I am missing some parts........It seems there is some kind of copper? contact connected to a spring that resides in the turn signal switch, and then makes contact with something that turns around with the wheel........I seem to be missing the part that turns with the wheel, and someone somehow has taken out the copper plug connected to the spring inside the turn signal SWITCH.....My question, How hard is it to remove the turn signal switch, ( I have removed the three phillips screws, and it doesn't seem to want to come out), are the wires connected to it removable, and where can I buy (if possible) these parts? Thanks for all the help.............
