take a piece of thin plastic or something and drill holes for the shocks to mount through. thats what viperdout is trying to explain. it works very well and keeps your rear end planted instead of hopping around like stock or even a mono-shock which i think is worse..
adding a bar it makes the rear suspension work as one, as well as with varying lengths you can adjust camber settings. i am using a cut up broken guitar pick cut short for a bit of negative camber. makes the rear end much more predictable, especially with lsd.
