What you will need is the rear trailing arms from either a VR/VS irs.It doesnt matter if its a 6 or 8.You will need the discs and drive shafts as well.
I will try and cover everything
1)jack up rear of car and put on stands.
2)remove wheels
3)remove drive shaft using an 8mm allen key(i got a kingchrome one that fits on a ratchet and i saves heaps of time.You will have to put the hand brake on so the shaft wont move while undoing.
4)undo swaybar 13mm
5)remove spring
6)you will need to undo the metal brake line that goes from the arm to the flexible line that goes to the body(they are tight and best done with vice grips).
7)remove the spring that holds the hand brake cable to the hand brake and remove cable.
8)the arm should be now hanging by the two mounting pionts on the body.
use a 19mm socket and a spanner to undo the nut and bolts.
9)the arm should now be free to remove.
You need to use your original calipers,flex and metal brake lines,as the fittings may be different.
10)remove the calipers and brake lines from original arms as you will be putting them on the VR/VS arms.
11)fit these to the new arms.
The arms are now ready to be fitted using the same removal process in reverse.
12)use some low strength loctite on the hi tensile bolts for the drive shafts.
13)when you go to reconnect the hand brake cables you will find they will be too short so you will need to adjust them up near the transmission.(you will see what i mean)
14)the brakes will now need to be bled as there will be air in the system.
15)double check every thing is tight
If i have got you confused PM me and i will ring you to help.
Thankyou.
