Warren,
If you are not taking the driveshaft out of the torque-tube (for a rebuild or a R&P conversion, for example), that bushing (often called an Okie bushing, no offense Greg_H) seems to be the almost standard choice.
Some people simply push in the old bushing/seal and install the repair bushing (easier). Removing the old bushing/seal is a "cleaner" procedure.
In some years, there is a pin through the outside of the torque-tube into the original bushing which has to be removed/drilled-out(?). Maybe someone will post clearer information or post a link to an earlier discussion that better describes this?
