Horn Cam for aftermarket steering wheel?

[elorenzof]

Im putting on an aftermarket steering wheel in my 1970 c10 w factory column. the new steering wheel has a different horn cam setup than factory. the metal prong that springs in and out / sticks out from the factory cam is built into the cam itself. the new one has a wire attached to the metal prong that springs in and out and i need a horn cam that i can put this new prong into, can anyone help with suggestions? Please see pic of factory horn cam and the aftermarket cam button / spring / prong thingy. I know that there has to be someone else that had this small issue to get his or her horn to work ~ Lorenzo
