should be stuck to the underside of the wing and paint black to blend with the wing and protect from water.
The wing lamps can now be fitted referring to section 9 Wiring.

Upper Steering column

To fit the steering column start by making a simple template as per figure 21 (6mm plywood is sufficient).
Using the template located on the two warning lamp holes, position the column with the top mount against
the scuttle hoop flange and the lower mount against the sloping part of the bulkhead with the lower part of
the column passing through the centre of the hole provided.
While the upper column is in place offer up the lower column and universal joints to check all alignment
correct, the lower column may be too long and can be shortened later. Mark the centres of the 2 holes
required to bolt the upper steering column flange to the scuttle hoop flange and drill 2 holes 6.5 mm through
the sloping bulkhead into the lower flange in contact with it to mark the centres. Look at the space between
the column and the bulkhead, this will need packing like the wing stays to leave a flat mount area and to save
damaging the bulkhead when tightened. Mark the area where the column lower plate covers the bulkhead
before removing the column and drill out the 2 holes in the scuttle hoop flange 10mm, and the two holes in
the bulkhead flange 6.5 mm.
Protect the column with masking tape before spreading a coating of freshly mixed filler paste on to the upper
surface of the mounting plate and refit and bolt in the column so the filler squeezes on the underside of the
bulkhead and conforms well with the GRP surface.
Once the filler has dried remove the column once more to clean both column and bulkhead and paint
bulkhead filler to match the bulkhead. While the column is out install the ignition key, this can be done later
but it's easier to do out of the car, the column can now be fitted permanently back in place.
8.3.6

Lower steering column and escutcheon

Before fitting the lower column the upper column needs a stainless cover escutcheon fitted, this should have
a rubber seal behind it cut to suit the upper steering column and can be fixed with two screws. The lower
column can now be fitted into place using the universal joints, make sure the upper column has the indicator
canceling lever to the right and the wheels are in the straight ahead position. Fit the column with the longest
spline to the steering rack, this is the spline that can be shortened if required due to the different types of
steering racks available.
8.3.7

Throttle pedal

Fit the throttle pedal to the lower sloping part of the offside bulkhead, see figure 9. The dimensions given are
a guide only and the pedal should be offered up and free travel checked before drilling two 6.5mm holes. Fit
it with the 1/4" UNF x 3/4" set screws & nyloc nuts. Using the pedal, mark the location of the hole needed to
accommodate the throttle cable. Drill the hole to the appropriate size for the cable gland supplied. Fit the
cable to the pedal and the engine and check the throttle operation.
8.3.8

Choke cable

The choke cable can be mounted in its own plate if preferred or in the mounting "Z" bracket that can be
supplied by Suffolk Sportscars for fitting and auxiliary switches or sockets. This switch panel is mounted
behind the wiper strap using the same bolts and sticks out under the wiper motor. Run the cable without any
sharp kinks through any hole in the bulkhead that suits the root needed to reach your chosen type of
carburetors and connect it to the linkage testing that it pulls in and out without jamming.
8.3.9 Door latches and strikers
Fit the door latches to the doors using fig 10 as a guide. Drill and tap the door M5 or 2BA. There is a steel
plate moulded into the GRP. Fix with slotted cheese head machine screws. Remount the doors and
fit the striker plates level with the door latches, drilling and tapping M5/6 into the doorposts and securing
with M5/6 x 25 polished stainless or chromed dome head countersunk screws. Adjust the door latches
and/or striker plates with packing as necessary to obtain satisfactory door closure. Remember that this is
temporally and will have to be readjusted following the fitting of trim panels to the doors.
