Lost my Fuel and Temp Guages at the dash in my 67 Dart

Both gauges, fuel and temp, always go out at the same time but the rest work

There must be a common intersection of some kind.

The 12v feed to the IVR will do that.
The pin (red dot) or the slot (red dot) can do that
The pins are circled in red and are notorious for failure.

I did remove the dash screws yesterday and pulled the dash out about an inch, got scared and put it back in

It is a challenge to remove the dash cluster.

1. Easiest is to remove the front seat/s
2. The steering column
3. Unscrew the fuse block from the dash
4. And tape off the dash and the switches to protect from scratches.
5. Disconnect the speedo cable
6. Remove the dash screws and tip the cluster out as much as possible
7. Remove the nuts on the ammeter gauge
8. Carefully remove the two rectangular connectors
9. There is a clip above the speedo cable that holds the wire harness in place it moves straight forward of the car to move it off the clip.

Then the cluster can come out of the car.

NOTE:
the wires, connectors, nuts, the clips etc are all old and can be brittle.



Important Note
When the cluster is unscrewed there is no ground to the cluster and you can / will fry the gages

As Dana67Dart suggested it seems like a ground or a loose connection in the instrument panel, what connection would affect both gauges besides a ground? Understand the IVR unit could be the culprit, BTW where do you get those

The green dot on the board is a ground point there are several others.
