I could be wrong Greg, but I believe the rear end suspension on his 700 and your 200 are entirely different. You have parallel upper/lower control arms -- locating arms on the bottom; torque arms on the top. He has lower locating arms, and a single torque arm that mounts in the center of the rear axle near the bottom of it, and runs up a couple of feet to a mounting point offset a bit to the side of the driveshaft. I believe the bushings he's speaking of are for the lower control arms.

If you want torque arm bushings for yours, you can buy two adjustable torque arms with poly bushings for about $125 from IPD.
