
½" drill bit, drill, ¾" wrench, ¾" socket, ratchet

Rear spring perches, Mustang springs and rubber isolator mounts
Hold the spring perches up to the frame so the vertical perch mount is in between the 2"x 3" tube and
the vertical frame mount.
Mark the location of the holes on the bottom of the 2"x 3" tube with a marker.
Drill the two hole locations all the way through the tube using a ½" drill bit.
Bolt on the perch using the ½" bolts provided.
Thread the cut rear springs onto the conical frame mounts all the way.
Insert the cut rubber spring mount between the spring and the steel seat. Make sure the end of it is flush
with the end of the spring mount.

Suspension height adjustments are done in the rear by turning the spring from its normal position
on the mount to a position higher or lower. Remember that the spring is located halfway to the
arm mount, so any height changes at the spring will be multiplied by roughly two at the axle.
