I went with a vacuum gauge instead of a clock. As I recall, the number of gauges that will fit that hole is a bit Limited .

Yea the only repo clock I found that'll fit is like $140 I can't justify spending that for a clock. I was hoping to find someone with an old one they no longer need. I might just go with a vaccuum gauge

Jeep CJ Gauge & Sender Diagnostics
by John Foutz
This article only covers gauges and sending units used in the AMC Jeep CJs built from '72-'86, but some of this information will be useful for owners of other Jeeps. There are some slight variations with the Jeeps built from '72-'75, but starting in '76 things remain pretty consistent for 10 years.
About the Gauges
The meter movement in all the gauges have a built-in dampening mechanism which keeps the needle from bouncing around. The dampening mechanism is basically some thick grease on the movement's pivot points.
The reason all the meters are dampened is because the senders do not have a very constant resistance. If you put a good testing meter on the sender while the motor is running you will see the resistance bounce all over the place. The dampening averages out the reading. This also is why it takes a few seconds for the needles to come up to position instead of snapping to a reading.
When ordering replacement Fuel and Temp gauges for your Speedometer cluster, Stewart Warner brand are considered the best. These have "C" and "H" as well as the "E" and the "F" in the stock OEM orientation.
Imported after-market gauges have these ranges reversed, both are 12v, and have a different wiring and post setup. Use their instructions and diagrams during replacement.
About the Sending Units
The oil pressure sender is similar to the fuel gauge sender. The mechanical parts are different, but after that it is basically a coil of resistance wire wrapped around a card and the wiper moves across the winding to change the resistance. The higher the fuel level or engine oil pressure, the lower the resistance. With less resistance, more current flows and the gauge reads higher.
The oil pressure sender and fuel sender are both electro-mechanical devices but the temperature sender is not. The temperature sender is a temperature dependent resistor (Thermistor). The type in the Jeep is a NTC (Negative Temperature Coefficient) which means that as the temperature goes up, the resistance goes down.
Gauge Sizes
Gauge Diameter
Oil Pressure2"
Volt meter2"
Tachometer2-7/16"
Clock2-5/8"
Speedometer cluster5-5/8"
Fuel and Temperature Gauges
From the passenger side which is left to right in the picture above.
The Jumper/Regulator Strap is composed of two strips of metal that continuously make and break contact, regulating the output to the Temp gauge to 5 volts. A volt meter applied to the A terminal on the Temp gauge should fluctuate (plus and minus) near 5 volts. A reading of 12 volts on the temperature side indicates a bad Jumper/Regulator Strap. 12 volts applied to the temperature gauge's A terminal will cook the gauge.
Fuel Gauge
The fuel gauge should have the following resistances ...
To be sure the problem is not the gauge, you can momentarily short the pink wire on the output of the sender to ground, and this should show up as FULL on your gauge. DO NOT hold it for very long in this position. If the gauge does not move from EMPTY either the wiring has an open circuit (no voltage, or no connection to ground) or he gauge is bad. If it does move, the sending unit is bad.
The sending unit can be checked with an ohmmeter to measure the resistance between the round sender post (pink wire) and ground. It should be:
Resistance Reading
73 ohms Empty
23 ohms1/2 tank
10 ohms Full
If the resistance falls in this ballpark (depending on how much gas you have in the tank), then the sending unit is fine. If it shows infinitely HIGH resistance, then the sending unit could be bad OR the wire from the tank to the gauge could be open.
The gauge can be tested with the resistances listed above. Run an appropriate resistor to the S terminal of the fuel gauge and to ground and check the readings.
Temperature Gauge
The temp gauge has the following resistance ...
Totally Cold high resistance
Slightly Warm 73 ohms
Beginning of Band 36 ohms
End of Band 13 ohms
Hot 9 ohms
If an appropriate resistor is connected to the S terminal of the temperature gauge and to ground, the above restances can be used to check the gauge. Use a resistor close to the specifications above to simulate the sending unit.
Oil Pressure Gauge
From the passenger side, left to right in the picture..
To be sure the problem is not the gauge, you can momentarily short the wire from the output of the Sender to ground. If there is no resistance, your gauge should read 80 psi. DO NOT hold it for long in this position. If the needle does not move from zero psi then, either the wiring (open circuit) or the gauge is bad. If it does move, the sender unit is bad.
It is very common for the sending units used with the AMC 258 i6 / 4.2l and AMC 232 i6 engines to be inaccurate. Make sure you have a good connection to the sending unit.
It is easiest to test the sending unit by temporarily plumbing in a good mechanical gauge.

I have two brand new never worked gauges from Crown,Tach@Clock!
I think there has been some writeups at the other Forums on this,My advice is to stay away from These.

you may be right about there product as I have no first hand experiences with them , if I ever want to replace mine I would like to add these but the price is scary Dakota Digital - Digital Instrumentation and Accessories
also these might be good http://www.autometer.com/cat_gaugedetail.aspx?gid=3071&sid=13
and summit sells Stewart Warner gauges which I have heard are good but still no first hand experiences
