Continuing the discussion from Changing rear shocks in a 2002 gem:
I recently replaced the shocks in my 2002 Gem with the NEV replacement shocks.They enclose a spanner type wrench adjustment for the 5 settings on the shocks. It looks like something that you would get with an IKea bureau. After trying it one one shock for about 15 minutes with no luck. I went into my basement and got 14in pipe wrench and adjusted all for in about 5 minutes. Highly recommend that approach!
