Was what i was looking at but its a rosta and i read will only work aftermarket and not oem with out relay any idea on a gm switch that works

The only factory switch that will bolt to an old column, the single screw type, is one from an 83 Chevy truck. 81-83 or maybe 84 will work but some are 3 wire switches and need the switch chabged.
