69^( BARRACUDA** gas (FUEL) Sending unit

Looking for a gas sending unit to send off for rebuild. Don't want a repop. Must be an Original Mopar unit. It doesn't need to function properly because I will get it overhauled before I install it. Overhaul costs between $100 and $175 so I'm not looking to send more than $30-$40 (plus shipping). Would prefer one that is not corroded or "jacked up". I believe the following units are interchangeable:

1963-1976 dart-demon
1964-1976
duster scamp valiant barracuda
5/16 line

Please post pics of what you might have......

Thanks,
Treblig
