The placement of the axles is going to depend on the gross trailer weight. I have included a picture that shows how to determine where the center point should be between the axles.

Placement of the hangers is going to require mocking up the hangers to determine where they are going to fit. But as a guide you can use the following as a starting point:

Distance between front and center hangers and between center and rear hangers, approximately 29-1/2 inches (74.93 centimeters).
