I thought the same, Dan, but I think I remember my last set of poly torque rod bushings being one piece. Now you're making me doubt that memory.

Edit to add: I just checked the IPD website, and the new torque rod bushings appear to be one piece. I remember thinking that the old two piece bushings were a breeze, after I fought with the new ones. They take a lot of pressure, and are very difficult to keep straight while you press them in.

Nevertheless, use a vise.
