I installed an MII kit from Progressive
http://www.progressiveautomotive.com/street.htm The installation was so easy I did it twice - DOH! {Mark the axle centerline on the frame (drill a small hole so it doesn't get ground off during prep) before you remove the sheetmetal!}
It rides fine and has stood up great to three years, 29000 miles of 4 season driving on Illinois roads.
