'68 Barracuda Notch

The odometer/trip wasn't working and I've determined that the plastic gear that controls that operation is stripped. Not surprisingly, I have a '67 speedometer with the screw in cable, unless it was a mid year change to the clip on style in '68. Looking for a new gauge now.
I'm not sure why the factory oil pressure gauge isn't working, so that needs some more investigating.

I have the part for the back of the speedo with the plastic gear it is not difficult to replace. But need to know if 67 screw on or 68 clip on speedo cable.

If all other gauges are working and oil wire is plugged into sending unit. With the oil pressure gauge you can use a grounded 10 ohm resistor at the sender wire it should go to full.
