Then that A100 may be as close as can buy new.
I have the one Dana bought. I gave him the original from my car as he had a rusted orignal but has the correct resistor board. I lost the resistor board (prob in the tank) and switched to 3/8 pickup. Didn't want to cut up up an orignal 5/16 tubing in an attempt to convert to 3/8.
Its so frustrating. Wish I had some connection to get the correct resistances wound into a replacement fuel sender. Same with oil pressure senders.
Almost as frustrating that no one sees the market for small runs of Anco pushbutton refills. Used on millions of cars - not just Chryslers.
