That was too easy -- what did I miss?
Can anyone point me to an op amp circuit that could be used to convert

How about a resistor? You could follow it by an opamp buffer if you needed lower output impedance.
What I didn't say was that your post was lacking detail, like inverting vs. non-inverting, and what frequency AC, and whether you could stand some non-zero input impedance to the thing.
If the frequency is low and you can't stand non-zero impedance then use
2.4V for "ground" and follow my circuit with another inverter. If you can stand a non-zero impedance to ground then use Bob Monson's resistor to 2.4V, possibly followed by a non-inverting amp that's also referenced to 2.4V. If the AC frequency is high and you must have zero impedance to ground then brush up your resume.Etc.
I really like the ascii circuit generator you used, by the way. I'll check it out.
What *I* missed is that I needed it to be non-inverting. :( The common mode voltage is going to be about 2.4 V instead of ground.
