As long as the voltage at the ends of the shunt are about 3V more positive than the VSS pin; and about 5V more negative than the VCC pin, and the voltage between the VSS pin and the VCC pin is 10V or more, then a crappy old 741 might work.
Do your self a favor and buy some modern CMOS rail-to-rail INPUT, rail-to-rail OUTPUT opamps and throw the 741s as far as you can throw them. I have some CK722 transistors in my junk box, but I will never use them in a project....
