On my '74 260Z, what could be wrong with my water temp, fuel level, amp meter, and oil pressure gauges? I'm not sure if the clock works or not. All of the gauges light up, but none of them work. My tach and speedo work fine.
Also, what are the two knobs for under the dash on both sides of the car? They pull straight out, but I'm not sure what they're for. Also, the car has two brackets directly under dash under the glove compartment. they have a hole drilled in them with a rubber insert. What are they for?
