I've gotten the old shock out and the new one in place. Unfortunately the threaded rod that comes out of the top of the shock isn't long enough to clear the new rubber cushion and the two retainer plates so that I can thread on the new top nut. I thought maybe both sets of cushions and retainer plates were supposed to be below the attachment point on the body, but the FSM clearly shows one above and one below. How have people solved this? Squashing down the upper cushion somehow? Or is there an easy solution that I'm too boneheaded to figure out?
