I've got this gauge problem. My 164 had a rotten gauge cluster

and I found a GT cluster in a salvage yard. Cool. Except the

fuel and temp gauges were shot. Rats.

So, I've been looking in salvage yards to see what I could put

in their place, and I discovered that every 240/260/280 Z / zx I

looked at had 2 small round gauges that are exactly what I want:

coolant temp + oil pressure

fuel level + voltage

They're both small round gauges that I am going to measure to

see if they'll fit into the holes in the GT cluster.

How does the voltage sensor work? Just run wires to the fuse

box and ground and that's all? The oil pressure + idiot light

sender is quite large and I assume metric -- could I just get an

elbow fitting with metric on one side and standard on the other

to go into the old oil pressure hole? Suggestions on where to

get such a thing?

Also, the current temp + fuel gauges are 5 volt gauges. Any

idea if it is standard to use 5 volt or 12 volt for these sorts

of gauges? (specifically will the datsun gauges expect 5 or 12

volts? If they expect 12 volts can I just bypass the temperature

regulator to give it 12 volts?)

Correct replacements don't seem like they'd be too easy to

get -- my options are to grind open the old gauges and fix the

guts, put in somewhat incorrect gauges, or put in these datsun

gauges that have lots more information that I'd want. Choices

2 and 3 seem about equal in cost so I'd like to go with 3 if it

is possible without screwing other stuff up in the process.

opinions?

Thanks,
