That way too you don't have to worry about left or right swing.

I prefer to set the new blank in the existing jamb to mark the hinge locations. While keeping the hinge side tight aginst the jamb, you can slide the door up to the head jamb with a pry bar under your foot or a couple of wedges, and see if it fits true, if not, you can trim the top of the door parallel, then reinsert to mark the hinges.Don't forget to insert a spacer at the head before marking the hinges. The black plastic Porter Cable jig works good, for about $20. Make a couple of practice cuts on the old door edge to get comfortable with locating the jig, and take your time, they will rock easily if you are not carefull with the router.
