Having seen a fair number of threads over the past year or so from other '66 C body owners with troubles similar to mine, I now happily report there ARE GOOD SOLUTIONS available to us! For gauges, Autometer makes an EXCELENT unit matching the specifications for our old machines, billed by Jegs as: Auto Meter Officially-Licensed Mopar Classic Fuel Level Gauge 2 1/16 in. Electrical (Short Sweep) I was blessed to find their last one on their shelves, which I got to accompany a new fuel sending unit, obtained directly from the vendor (Not ePay!) here: eClassics 1965-1966 Chrysler Newport Stainless Steel Fuel Sending Unit 5/16" I LIKED the LOW PRICE! $34.50 for a WARRANTED FUEL SENDER has been UNHEARD OF UNTIL RECENTLY!!! It worked perfectly out of the box too. I read 10-~75 ohm on my cheap voltohmeter I keep in the trunk, and read the same with my Micronta meters later. But nothing availed until I got that Autometer gauge! I made sure the tank had only a few gallons in it this morning when I installed this, as shown, cabled tied down to the old instrument panel bezel by the shift indicator. It read just up to E then, when powered up. I filled the tank to slopping over full, then sent the Babushka this pic to assure her the near C-note we spent on the C Body (shipping and extended warranty added to the $65 price.) was WELL WORTH IT! So it is Fellow Moparians; Made in the U.S.A. by American Workers! If y'all still have Gas Gauge Blues, I've now shown you how to beat them.
