we are trying to get the dash back together in the 58. struggled all day to day to get dash lights to come on. the rust and corrosion would not let the circuit in the switch work. so it's held together with screws lets take it apart! you get that last screw out you better be in a enclosed box. springs and things go flying.then it's one of those 4 hands and two levers to get back together with all the moving parts under tension. but apart you can clean it up and if you find all the pieces and hold your tongue just right you can have a instrument cluster that looks like this.
