Line up the motor stands with the
mounting bushings on the K-member. It may be necessary to shift the K-member or the motor slightly
to get the holes lined up. Once lined up, position the other polyurethane bushings and supplied 2”
washers on the bottom of the K-member mounting bracket and insert the supplied 3/8” bolt. The
