I bought a Repro Temp sending Unit From Dennis Carpenter. B6C-10884-A. Not keeping constant setting. Has anyone else had a problem with One of His senders? I would have preferred NOS but impossible to find. Thanks!

I bought one a couple of years ago and had the same issue. No reading and then suddenly it would come good. I think the issue is that it is a B6C 10884 without the A on the end. I suspect that it is fine for a light but no good for a gauge. They do come up NOS on Ebay occassionally. I bought one to replace that unit and also bought a spare about a week ago. There's one there now but it's very expensive.

My experience has been that the gauge & sending unit should be a matched set.
When I converted my dad's (now mine) 55 Tbird to 12v, I retained the original gauges and sending units. Although I question the accuracy of the original gauges, I saw no appreciable difference in their accuracy once I converted to 12v. I have since bought Autometer electric temperature, oil pressure, and voltage gauges and sending units, but the original gauges will be retained as well.
When I sent my B intake manifold to Ted Eaton for porting, he also drilled and tapped it, just to the right of the thermostat cavity, for a temperature sensor, having said that the location provides a more accurate reading that the location at the rear of the driver's-side head. I later drilled & tapped my Mummert intake in the same location for the Autometer sending unit.

I have a mechanical Temp gauge in the front of Manifold next to thermostat housing. it works fine. the original dash gauge has always worked fine until i took engine apart last fall. now The Sending Unit that was working fine quit. Bought a Dennis Carpenter replacement which seems to be the only one available no matter where You buy it. Not working consistently

There is only One sending Unit used for 56 Cars and Trucks for a Gauge only. No Lights were ever used for Temperature.B6C-10884 or B6C-10884-A are same application. Finding an original is hard and right now the only one on Ebay is not in my price range.

The orig. sending units (& gauges?) tend to read high eventually. NOS replacement brought the needle back to center. More reasonably priced units may turn up eventually. Just check ePay regularly.
