cup set screws into the bottom of the Stealthbox,
leaving about 1” of each threaded rod exposed.
Make sure that the slotted end is exposed.

STEP 13: With the Stealthbox in place and a sec-
ond person pushing down, it is time to mount the
Stealthbox into place.

Double check the socket cup set screws for proper
exposed length outside of the vehicle. Use a large flat
blade screw driver to adjust the threaded rod length.

The front threaded rod is not going to be easy to
access.There is a fast simple way and a more time
