IMPORTANT—All appropriate safety equipment (e.i., gloves, tools) must be used during the installation
of
this product(s).
BBK Performance, Inc. accepts no responsibility
for
injuries resulting
in
the installation
of
any
product(s).
IMPORTANT NOTE!!!
Some Mustang Cobra models and convertibles require removal of
one bracket on each sub frame connector to clear extra bracing used on these models.
Once the bracket is removed these sub frame connectors will need to be welded in
place.
Step 1
Support vehicle on drive-on ramps,
or
by placing jack stands under rear axle and front control arms (this
preloads
the chassis correctly by putting normal pressure on the
suspension).
Step 2
Place connector over the front and rear sub frames, making sure the bar
fits
flat against the sub frame and
con-
tours
to
the floor pan with the slanted end plate towards the front
of
the vehicle. Be sure bars clear all brake,
fuel
and vacuum
lines.
Step 3
Tack weld bar (front and rear)
to
hold
in
place, and then finish welding all seams. Care must be taken when
welding
heavy-gauge connectors
to
thin-gauge sub frames, too high heat setting can
“blow”
holes
in sub frames.
Step 4
If
you wish
to
bolt the connectors on, the exhaust system at the mufflers may have
to
be moved out
of
the way
or
completely removed
for
clearance
of drill.
Repeat steps
1
and
2.
Step 5
Using a
3/8” bit, drill
through both the connectors and the sub frame. Place
bolt
through hole before drilling next
hole (this keeps bar
in
position correctly and ensures an exact tight
fit).
Step 6
After all holes are drilled, install lock washer and nut
to
each bolt and tighten
to
25-35
ft. lbs.
Step 7
On models equipped with seat support brackets, simply install supplied lock nuts and flat washers
to
the
existing
seat studs protruding through the brackets.
If
a gap
is
present between the seat brackets and the floor pan,
1/2”
flat
washers may be used as a spacer
to fill
the
gap.
