Just installed a set of coil springs on my '89 LWB. the donor was a '99 Montero (Thanks to M&S recycling).
This was an incredibly easy mod. As Phil wrote in his article "Budget Lift", the hardest part was raising and securing the truck to work under. But with a little help from my Massey Fergusson 165 (High Lift <img src="/forums/images/graemlins/coolg.gif" alt="" />) this was not that bad. Job took 2hrs to complete, only because I was able to lift the truck all @ once.
I did not have to disconnect the shocks, just used a short prybar and the old coils were out. The old springs being 2" taller than the new made installation a breeze.

Result: Exactly 2" of lift
Now for the new shocks & a test drive <img src="/forums/images/graemlins/kewl.gif" alt="" />

Thanks to Phil for the excellent instructions in his article, and for his encouragement <img src="/forums/images/graemlins/cheers.gif" alt="" />
