arsw1 - you are right - it does say threaded. In THAT case, you need to consider two things - cost of having a fork race installed (probably not super expensive at your LBS) and probably having the steering tube cut down for your head tube (depending on the length it comes to you in and what size bike you've got). Specs say 178mm, measure your current fork's steering tube to compare. Good luck, and there's no stupid questions around here. Unless you ask what OCP is.
