Is there a source for factory original/correct repro fuel sender for 1968 Dart?

Hi guys,I’m working on getting my 1968 Darts fuel gauge working again. Someone’s replaced the sender before I bought the car with one of the new Chinese ones. I’ve heard here that those are garbage and won’t read correctly. Does anyone here know if any vendors are offering a factory correct sender that works correctly or is there anyone here with a factory original rebuilt one that’s for a 68 dart 270?
