How do you know what length radius rods.?

Frame is slowly coming together and and I am about to order my front radius rods.How do you know how long they should be..?

Usually the length is determined by the mounting location. Also your drag link should be about the same length as the radius rods and the steering box should be mounted so the drag link is parallel to the radius rod so as to reduce possible bump steer.
