One of the 261's I've got stockpiled is the late model with the dowel pin. I'm planning to drill and tap the dowel so i can pull it out with a slide hammer, a jack screw, or something similar, and thread the hole so the passageway can be opened or closed with a screw-in plug instead of a pressed-in dowel. I'll feel a lot more comfortable with a threaded plug and a lock nut controlling the oil flow!
