    You will need a conversion u-joint, 2ea 3" exhaust clamps to mount the sway bar, your old Brake Backing plates from your 10 bolt. Not too bad of a install but you will need to "pound" the sheetmetal up around where your torque arm mounts for the torque arm to clear.

    I would recomend Motive Performance gears. They are strong and Quiet.

    My cars has been whining on the highway pretty damn loud and the guy keeps saying its because of the stock u joint but I thought the stock u joint and torque arm would only cause vibrations not whine...also the sway bar is hitting the differential a slight bit

    he says i need to change the torque arm also and sway bar
