Restoring down to frame. Pivoting triangle below back shock has 2 sleeves, 1 on either side, inside the frame within the foot peg bolt holes. They hold the forward hole of the triangle in after the pin is removed. Foot peg positioning guides narrow the outside bolt holes preventing removal outward and prevent getting a socket in to drive the sleeves. Appears to be the port side sleeve needs to be driven inward to drive the starboard sleeve over to the right to allow the triangle's removal. The sleeves appear to then need to be driven all the way inward to remove them. I've found no write-up of this anywhere; been searching online for 2 days. Not covered in the Kawasaki service manual. Am I on the right track? I had to hammer out the pins to remove them. How do I remove the sleeves without damaging them, or are they considered expendable? I'm stuck, pun intended. Cheers.
