Nevermind, I was doing the problem correctly but the book listed an incorrect answer. To answer my own question, you simply choose one of the points as the application point of the force. You then proceed to find the distance vector which is essentially the application point written in vector form. Take this vector and find the cross product with the vector representation of the force.
The problem is number 31 in Engineering Mechanics: Statics, by J. L. Meriam and L. G. Kraige. The correct answer is 518 N*m
