Original Fuel Sender for a 72 Dart

When I replaced the rusty old tank in my 72 Swinger, I thought I was being good boy by ordering a new Spectra sender to go with it. Only after the old sender was long gone did I realize how truly awful the readings are from a Spectra sender.

So before I go for a MeterMatch or similar wizardry to try and get an accurate reading of how much gas is in the tank, I figured I'd put the word out here to see if anybody has a used original sender. Old and crusty is OK as long as its rebuildable and (I think) from a 67-76 Dart. Lemme know what you got.
