Is this what you have?
PRO-TRUCK LIFT SYSTEM (Stage 1) - TOYOTA 4Runner Base
Just looking at pics of these and the 2.0 coilover the lower mount is obviously larger and good install directions. What they give for these is lacking. Only tells you how to set up the shock/warnings "after install" etc, no install information.
Did they send you the correct shocks for your year? Maybe mixed up the order??
Good luck.
