tower plate. There are three 10mm bolts in total. Two
bolts are located on top connecting the ecu bracket
to the shock tower plate, and the third is located at
the bottom of the ecu. The bottom bolt needs a 10
inch extension and universal joint to unfasten. Gently
move the ecu off the studs of the shock tower plate
and place a rag between the ecu bracket and the
shock tower to protect the paint. Do not disconnect
the ecu from the wiring harness. Figure 7.

the vehicle to the shock brace using the two included
M6x35 bolts, washers, and nuts.
