Installation Instructions For
LEX-RBC-MC: Monte Carlo Rear Bumper Cover.
We have made the installation instruction of the Rear Bumper Cover
as easy as possible yet we advise you to read the entire
instructions CAREFULLY. Take your time and use some
craftsmanship. The end results will be worth the effort!
Place both rear bumper cover and rear quarter panels on the ground,
as they will be installed. Line up rear quarter panels
against rear cover so they align properly. Drill a 1/4” hole
from rear quarter into cover, top and bottom, for both sides.
Remove taillights and housing from inside the trunk. Remove
license plate holder and original rubber fascia. Remove the
rear bumper and rear bumper shocks from frame horn, (3 bolts
showing and 1 bolt on the bottom of the frame horn).
If you would like to have some protection (and we strongly suggest
you do), you can purchase a piece of rectangular steel tubing that
is 58 inches long. by 2 inches wide, and 1 inch thick, (the steel
should be at least 10 to 12 gauge). For additional support,
two bars can be used and bolted to the top and bottom of rear frame
horns. Lauren Engineering makes no warranty, implied or
otherwise, that is product offers any protection what-so-ever in
the event of an accident or crash.
Drill holes in top of cover where the original fascia bolts on top
and sides. Place cover as it will be installed and secure
with original hardware and washers, (if these original bolts do not
stay tight, a 10mm hex bolt may be used for a tighter fit).
If any gaps between body and cover,-refer to Special Notes and
Adjusting the Fit.
Remove cover after fitting and install license holder. NOTE:
Some trimming may be needed, as original fascia changed in 1987 and
88. Place taillight cover on body. From inside the
trunk, mark and drill from original holes in the body.
Reinstall bumper cover, license holder and taillight cover on your
Monte Carlo. If the taillight cover does not line up, it will
need trimming on the bottom inside corners. If there are any
gaps between the body and taillight covers; refer to Special Notes
and Adjusting the Fit.
Once they line up, drill and install two 1/4 x 20 x 1” hex bolts,
washers and lock nuts, from bottom of taillight covers through the
top of the bumper cover. Place pigtail in the back of the
ZR-1 bucket and match the pigtail with the opening, (some fitting
and trimming may be needed). Install into buckets. Hold
taillights lens into mounting position and drill into tabs
provided, to install taillights. Install taillights and hit
