Buy the bushings from Figs Engineering.
First, jack up the car and remove rear wheel.
Remove the nuts and bolts holding the shock absorber, the swaybar link and the hub knuckle. I used a jack under the arm to assist in removing them.
As you can see, it is difficult to press out the bushing as there is no support in the middle.
Remove the arm and burn out the centre of the OEM bushing by using a Map gas torch. Burn out the rubber completely.
The centre sleeve will drop out. Be careful as map gas is REALLY HOT. Also, the melting rubber is messy and toxic smelling.
Use a hacksaw to carefully remove the old sleeve trying to avoid the sheet metal from bending.
Then knock the the bushing out. Be patient and it will come out. I used more heat and a few cuts.A bit of a sanding helps if the outer sleeve is rusty.
I used a socket and tapped it into the lip on the side to prevent the sheet metal from bending in when I pressed the new bushing back in. I used the g-clamp press tool that Figs Engineering recommends. Again, go slow and methodical. If you don't the sheet metal with just bend.
Add some chassis paint and all done. To re-install, bolt it back in. (in reverse order.)
Make sure that you point the offset in the correct spot. If it's wrong, you can press the middle sleeve halfway out again, adjust it and press it back in.
Do the same for the other side and get the car a prof wheel alignment.
