Replace gas tank and sending unit or not?

Your sending unit probably looks like mine did.With the age of these cars replacement is a good idea IMO.If the tank is clean inside I'd just replace the sending unit.You won't know till you open it up though.My 72 Dart's tank looked absolutely spotless inside,that car had been somebody's dd and probably never sat.Now My 73' which sat in a field for some time was another story the tank couldn't be salvaged.
