TURN SIGNAL

I'm tired of being the little old man driving down the road with my signal 
light on. I am missing the piece that goes on the steering column that 
cancels the switch. does anyone on the list have a spare steering column for 
a 74 midget that they would part with this piece? or a daigram of this part 
that i could possibly make one myself? Or somewhere i can order one? Help me 
stop being the one everybody cusses when following me. thanks
