Rear Spring Bushes

[murph-gsi]

Hi, I am just wondering on the rear of a nova does everyone have rear spring bushes/ insulators?
What is their purpose?
Is their a lower one also?
If any would have any pics of the the above would be great.
Oh ya link of maybe the ones I need.

Thanks, Chris

There is a large black rubber disc that sits at the top of each spring to insulate it from the body and stop any knocking or noise.
There is an alloy top hat shaped bit that sits below the spring on the rear beam spring mounting mount.

You can just see the top rubber on the coil spring on my Swing...

Alright cheers lad. Just remembered not seeing any on mine!? Are these an essential? It says it highers the car around 9mm. Or are standard ones ok? Thanks
