Ya got the hard part done Mike. Yes you will need to pull the pitman arm, pullers are avalable at Harbor Freight real cheap of you can't borrow one. If ya taint got one near you order it on line. A plain old pully puller probably won't be sturdy enough for the job. Soak the spline down with a good penetrating oil for a few days. Just take your time and don't butcher the spline or arm by beating on it with a BFHammer.
