Just curious, why are you replacing the turn signal lever? And the hazard switch is part of the turn signal switch, you are probably just missing the knob and screw to push the switch on! Sounds like a trip to the pull-it-yourself yard is in order :)
When I bought my truck, the PO had an aftermarket cruise installed, and hacked off the end of the original lever. So I got rid of the cruise, and got a chrome lever with the delay wiper markings only, for a mid 80's Chevy.
