STEP 13. Place the nut on the threaded rod.
STEP 14. Measure and cut the threaded rod with a
hacksaw. Use the chart, Figure 11, to determine the
length.
STEP 15. Remove the nut over the cut end of the
threaded rod. This cleans the threads after cutting.
STEP 16. Thread the cut end of the rod into the hub,
STEP 17. Install the ceiling plate. The rotate/lock
lever must point toward the rear of the vehicle.
Be sure rotate/lock lever is pointing toward back
of vehicle and hole in ceiling aligns with hole in
the ceiling plate.

STEP 18. Measure and cut the directional
handle; see Figure 12 and chart, Figure 11.
NOTE: A tube cutter is recommended for
cutting the directional handle. This gives a
square cut; a hacksaw does not. If using an
extension, see Step 22, page 9.
Figure 13, page 9, shows what points to
measure between, with and without a roof
wedge.
