Gas gauge

Hey guys, anybody know where I can get a replacement gas gauge for a 1984 d100? The wires connecting the gauge to the posts broke and in trying to fix them I managed to cut one off. Can't find any online and the local scrapyard didn't have any suggestions. Haynes manual says the sending unit runs 5-8 ohms when full and 60-75 ohms when empty. If I need to I can rivet the old face to a new gauge.
