BODYSHELL PROTECTION
the two holes alongside the suspension turret
and drill out to 10mm. A third 10mm. hole has
to be drilled at the point where the diagonal
support meets the front tower arm, but opened
out to 25mm on the outer skin of the chassis
member, to enable the fixing bolt to be inserted
and tightened. Bodyshell and rollcage tolerances
again may require spacing washers to be fitted to
` bridge the gap' between the tower arm and the
body panel prior to tightening the attachment
bolt. Again, use the 10mm. hole as the pilot
hole for the hole saw. The diagonal support
arm can now be passed down through the wiper
motor well area to the lower attachment point,
the front tower arm can then be positioned and
the assembly fully secured. Repeat this procedure
for the other side of the car.
Four heavy gauge washers and fixing blocks
are now left. These are for additional attachment
of the sides of the rear frame. Drill 10mm holes
through the INNER SHELL ONLY, at the four
rear frame side mounting points. Pass the upper
fixing block upwards inside the shell, position a
heavy gauge washer between the shell and the
frame, then retain by inserting the bolt. Repeat
for the lower fixing points. Check that all bolts
and component parts are in place and that you
are content with the general fit.
Now go round ALL attachment points and
thoroughly tighten all bolts.
The strengthening and preparation is now
complete but it is suggested that the roll cage
i s removed whilst the bodyshell is painted.
FRONT SUSPENSION BRACE
This is the last item under the general description
of body strengthening, and must be fitted to the
car by attaching to the front suspension top
mounting bolts. This can be left until all the other
operations have been carried out. Spacers may be
required to give adequate clearance between the
brace and the manifold on certain vehicles.
SUMP AND TANK SHIELDS
An undershielding kit has been developed for the
Group A car. This front shield protects the engine
sump and transmission assembly, and attaches by
four bolts to the front mounting points for the
forward facing, lower suspension arms. The rear
of the shield is attached by two bolts, adjacent to
the inner pivot points for the lower wishbones.
A threaded insert is already incorporated in the
strengthening plate supplied for this area and
should have been fitted during the bodyshell
preparations. The rear attachment points are
not pre-drilled in the sumpguard. These must
be marked out to suit the individual vehicle with
the front of the sumpguard correctly attached.
The holes must then be drilled out to size (12 to
12.5mm) for positive location of the sumpguard,
since this then becomes an integral part of the
chassis.
NOTE: The hole positions can easily be
marked on to the shield by the following method.
Remove the head from a 12mm bolt, screw
this remaining threaded portion into the rear
attachment point leaving approximately 5mm
of thread above the surface. Fit the shield to
front attachments and apply pressure to the
rear of the shield at each attachment point,
the threaded section should then clearly mark
the shield accurately where the holes should be
drilled.
The lighter gauge rear shield is profiled to fit
around the fuel tank area. The rear part of the
shield attaches to the rear tank mounting points.
Three holes must be drilled on either side of the
shield, for bolting through the floor.
