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 few feet to a mounting point offset a bit to the side of the driveshaft. I believe the bushings he's speaking of are for his lower control arms which I think are different than yours.

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