I don't have the original guide or any photo's but a quick overview:
Front -
Loosen the tophat middle bolt, don't remove the bolt
Remove bolts around tophat/hole (not the tophat yet)
Remove the two bolts in the bottom of the leg near the disk
Pull out the leg carefully
Compress Springs
Remove tophat bolt, then out comes the spring to replace
Replace tophat, components and bolt
Replace leg as removed
Rear -
Put car on axle stands at both sides
Remove bolt from bottom of the shocks (both sides)
Axle swings down so springs are 'loose'.. might be stiff to pull out the seats or may be compressing..
Add in new springs
Use a trolley jack to higher the axle back into position
Replace the bolts in the bottom of the shock and wa-la.
As for springs.. H&R's have a better stance but are twice as expensive!
