If you haven't read it already, check out my post from when I did mine:
viewtopic.php?f=4&t=27787&start=71- Strut brace can either be spaced up, or the strut tower metalwork massaged to fit (ie angle grinder and ball peen hammer is your friend). I think spacing it is a shit idea personally so would go the latter ever time. Do it neatly and you'd never pick it as not being factory.
- You will need to un-do the clutch lines (and possibly get a longer one made). GVs (and most suzukis I believe) have fixed studs on the body hence even though you just want to install a 1" lift you still need to lift the body a good 5 or 6 inches for you to be able to slip the new body block into place onto the stud.
- Steering shaft will need to be undone. You may be able to get away without a spacer, but it'll almost definitely need to be undone at least while you are installing the new blocks.
Remember to undo the fuel filler pipe also.
