All my Chevs use the bourdin tube gauge with the bulb on the end of the tube.

I have definitely seen Bourdon tube temperature gauges in civilian Chevrolets. I had always though it was a function of model year. Pre-war and wartime mechanical gauges and changing to electrical about the time they went to 12V, about 1955 (but not sure the two changes are linked).

Maybe my electric gauge is later manufacture altough it
does fit in the 1939-1946 gauge unit.

I'm also having trouble finding a GM/Chev electric temp sending unit, though in my case it's for a 12V system. I have tried a number of units for the block that look right and are NOS but don't work. My best guess is that they are designed for a dash warning lamp that is either 'off' or 'on' based on a predetermined temperature. What I need as a variable sending unit to read on the gauge. Any ideas?

Bruce, I don't think you should have much problem finding
a 12v sender. The sender should only have a single pole
and possibly be a TS-6. I have seen them on the internet
for 12v systems. I ve read that these are tested by
measuring resistance at different temperatures, by putting
them in hot water and cold water.

Default Comments on instrument cluster........

I am using a NOS GMC rectangular civilian pattern

I t came with a mechanical "bourdon" tube and greatly simplify my chabig to 12V.

Oil gauge is mechanical and works But has now been replace with a larger face circular oil pressure gauge mounted under the dash...... I wanted more info to monitor.... installation may be reversed at a later time.

Fuel gauge needed a voltage reducer to use with the my 12 v system........and with the two way fuel tank switch from Bob Phillips worked beasutifully. Both floats were replaced with repro.

I now have 237 miles on the odometer.

For the Speedo...... because I was using a GMC the fitting at the speedo head is a hollow square and had to have a cable made....... found a guys who works from home near Smiths Fall who for just under $100 made me a cable that fits the GMC head and the GM T case fitting..... steel with black vinyl coating...... bare steel sheath is also available but shunned due to rust deterioration...... he does a lot of antique boat tachometer and strongly recommends vinyl coating for all applications. Mine went on flawlessly.

That leaves the AMP meter which can be used as is even with voltage changes as it functions basically as a master connection for all other items that are going through it........ it basically shows if the charging system is putting out enough voltage / amps to satisfy the demand and with a a 75 amp alternator should never be an issue with a stock CMP......

My various toggle switches are all PA after finding that the NOS, still wrapped and sealed toggle switches, had badly oxidized inside the wrapping.

If you are curious, Ebay had a few listings for rebuilt Chev clusters just short of $1000 USA DOLLARS.....HO BUT WITH FREEE SHIPPING hA!!!
