Specifications

Please note that both front wings MUST be
removed for this operation.
Thoroughly check items supplied against the
component parts list to make sure that there are
no shortages. It is advisable with a complex,
multi-point cage such as this to loosely assemble
the cage prior to making any attempts to actually
fit the structure to the car. Reference to the roll
cage assembly drawing will give a clear indication
of the intended final construction. You will then
be more familiar with the individual components
and where they will eventually be secured. Once
this has been established the cage can be split into
sections ready for assembly into the bodyshell.
Position the rear frame alongside the body-
shell, and tilt it forward such that the mounting
points for the rear suspension turrets are upper-
most. Maintaining this position, pass the frame
through the door aperture, into the bodyshell
and locate the foot mountings onto the sill.
The frame, still tilted forward at the top,
can now be moved towards the rear of the
bodyshell, then turned to an upright position
and further rearward until the rear suspension
turret mountings can be located centrally onto
the rear suspension turret tops. Now drill a
10mm. hole on each rear turret mounting and
i
nsert a bolt. The rear part of the roll cage is
now located in its correct position.
Position the foot mounting brackets (Sill
Mounts), making sure that they are seated
correctly on the sills and accurately mark out
the six attachment bolt holes. Detach the rear
turret mountings and move the frame forwards
so that the six holes marked out can now
be made to 25mm diameter. Attach the foot
mountings to the rear frame and bolt up fully
before returning the frame to its fitted position.
Drill out the remaining rear turret mounting bolt
holes and fully attach with the 10mm bolts. The
foot mountings can now be welded in position
to the sills. It is important to clean this area
thoroughly to ensure good welding conditions
for this operation.
Now the two rails can be positioned and
attached to the rear frame with bolts. Fit the
front roof rail to prevent the side rails from
falling inwards, whilst the front frame foot
mountings are positioned on the sill. Mark out
and attach these to the sill in the same manner
as at the rear.
Two mounting blocks are provided, with tabs
to give additional attachment for the side rails.
These attach to the roof stiffening rail above
the door aperture. Position these, drill the two
holes and bolt into position. The door rails and
the front roof rail should be loosely bolted in
position at this stage.
There are two forward facing brackets on
each of the side rails, which are to carry the
arms that attach to the front suspension turret
area. The upper bracket on each side should
i deally be close to or in contact with the actual
door pillar at that point. However, because of
tolerances in both the bodyshell and rollcage a
spacing washer may be required to `bridge the
gap' prior to tightening the attachment bolt to
the door pillar. Using this bracket as a guide, with
extreme caution, pass a 10mm. drill through the
bracket and drill outwards through the shell until
the point of the drill JUST starts to SHOW on the
outside of the shell, then STOP drilling. Using a
hole saw, the drill bit acting as centre, open out
this hole to 25mm from the OUTSIDE of the
car through only TWO of the panel thicknesses,
LEAVING the pilot hole in the INNER skin at
10mm diameter.
The front suspension turret/front tower arms
can now be fitted. A template is supplied to assist
i
n marking out the holes required through the
bulkhead area and into the windscreen wiper
motor well for these front support arms. The
template is for the RIGHT side of the car looking
forwards, the position for the other side can then
be judged having completed the operation on this
right hand side unit. Take extra care when cutting
out these holes, it is better to make them too small
i nitially and progressively increase them to give
a close-fitting. This then leaves less of a gap to
be filled after final completion of the roll cage
i nstallation, and maintains compliance with the
fireproofing requirements. Now feed this support
arm into position from the front of the car and
bolt to the side rail top mounting. Mark out
