Pack 01 |Build Instructions
In the 1960s, Carroll Shelby’s Cobras dominated racetracks worldwide, first winning races coast to coast
across North America, then in 1965, winning the World Manufacturer’s GT Championship, achieving the
ultimate goal of defeating Ferrari. The Semi-Competitions were modified from full competition models
just enough to make them street legal. Only 29 models were produced, making them one of the most
sought-after American sports cars by collectors.
Your 1:8 model replicates the original 1965 Semi-Competition Cobra in intricate detail. From the
dashboard dials to the writing on the wheels, every piece is precisely reproduced.
In your first model pack, you will assemble:

AGORAMODELS SHELBY COBRA 427 S/C
Spare screws are included with each part. Occasionally, you may be instructed to keep spare or
unused screws for a later stage. Keep these spares in a safe place and label them correctly.
Please make sure you don’t mix up the screws. They look quite similar, but the threads do vary
slightly. Using the wrong screws may damage the parts.
When securing parts together using multiple screws, fit each screw loosely to ensure all the
parts are correctly aligned before gently tightening them firmly, but not overtight, in the order
in which you placed them.
The screwdriver can be magnetized by stroking it with a magnet (fridge magnet, etc.) enabling
it to hold the screws and make assembly easier.
If a screw is tight going into a metal part, do not force it as you may shear the head off. Remove
it and put a tiny smear of Vaseline, soap or light oil on the thread. That will lubricate it and make
it easier to drive home.
During the course of this build, you will receive many pieces that you will assemble immediately
– following the instructions in the corresponding stage – and other pieces that you should store
safely to one side, for use in future assembly stages.
Left and Right! When building your Cobra, the left hand side refers to the driver’s side of the car.
WARNING: Some parts are assembled using magnets. These magnets can cause serious injury
if they are swallowed. Keep away from children. If you suspect a magnet has been swallowed,
seek medical help straight away.

ATTACH THE RUBBER STRIPS
Take the hood and lay it carefully, upside down on
your work surface. It’s a good idea to lay it on top of
the Agora cleaning cloth, or other modeling-board
surface, so that you don’t scratch the paintwork.
Using a pair of tweezers, pick up a rubber strip, peel
back the adhesive backing, and position the strip on
the hood in the position shown. There is no specific
position for the strip. Press gently in place. Repeat
with the second rubber strip on the opposite side of
the hood.
ATTACH THE AIR INTAKE
With the hood in one hand, align the lugs on the
air intake with the holes on top of the hood, with
the gap facing forwards. Hold in place and turn
the assembly over to secure with three TYPE OP02
screws. Start by putting all the screws in loosely, and
then tighten them.

ATTACH THE HOOD HANDLES
Note that the hood handles are marked left (L) and
right (R).
Take the left hood handle and push it through the
hole on the left hand side of the hood. From the
underside, thread a gold-coloured hood latch over
the protruding handle, followed by a spring and
then a hood lock ring. Secure these components in
place using a TYPE OP01 screw, checking that the
components are oriented in the direction shown
before tightening the screw. Repeat for the handle
on the right hand side. Be careful not to over tighten
these screws as you can easily strip the threads.
Keep your Shelby badge for assembly at a later
stage.

ADVICE FROM THE EXPERTS
You may find it easier to place the hood
lock ring on the screw and then screw
this into the handle stem. (This reduces
the risk of the lock ring being catapulted
into orbit by the spring).

STEP 1
STEP 2
SOFTEN THE TIRE
The first step in assembling the wheel is to soften
the tire by soaking it in a hot water-bath, filled with
water straight from a kettle. The water must be very
hot, so take care, and have everything in place and
ready before you start.
Soak the tire in the water-bath for five minutes.
ASSEMBLE THE WHEEL IN THE RIMS
While the tire is softening in the hot water, assemble
the rims. First, place the wheel inside the outside
rim, aligning the screw holes. The wheel should
project into the rim so the screw holes sit flush.
Secure in place using 4 x OP03 screws. Then take
the inside rim and fix it to the outside rim and wheel
assembly, aligning the screw holes. Secure in place
with 4 x OP03 screws. Insert all 4 screws loosely
before tightening any of them.

STEP 3
FIT THE TIRE TO THE RIM
Remove the tire from the water-bath and dry on a
cloth or kitchen roll. Take care, it may still be very hot
so use tweezers to remove it from the water.
Hold the wheel assembly at a right angle to the tire
and push halfway through the tire before sliding it
into place. Firmly ease the tire around the wheel.
Fitting the tire requires some force, so push hard
and act quickly while the tire is hot and soft enough
to stretch.

ASSEMBLE BRAKE COMPONENTS
Push the hubcap into the center of the three-eared knock-on. This is
a friction fit and will stay in place without screws. Align the wheel hub
with the brake disc and position the pieces together. Align the tiny
hole on the brake caliper with the tiny lug on the wheel hub. Position
the pieces together and secure with a TYPE OD01 screw.

COMPLETE THE WHEEL
Place the wheel hub assembly in the inside of the wheel,
aligning the lug on the brake disc with the corresponding
notch on the wheel. Secure in place from the outside of
the wheel using a TYPE OD02 screw. Finish by placing the
knock-on assembly in the center of the outside wheel.
The knock-on assembly is magnetic and will stay in place
without screws.

Assemble the steering wheel by pushing the Cobra
emblem into the recess in the center of the wheel.
Ensure you have it in the correct orientation – as
shown – and push firmly.
ASSEMBLE THE EXHAUST PARTS
Take the exhaust pipes and align the lug on the
exhaust tip with the notch on the exhaust cylinder.
Push the two pieces together. You will add more
exhaust pipes to this assembly in the next stage.
The steering wheel, seat and roll bar are ready for
assembly with new components at a later stage.

STEP 1
ASSEMBLE THE AIR FILTER
To start assembling the air filter, take the air filter
bottom in one hand and wrap the air filter grille
around the ridge on the circumference. The grille is
the same both sides, so may be fixed either way up.
Hold the grille in place with one hand, and place the
air filter top on to hold the pieces together. Use a
pair of tweezers or screwdriver to tuck in the end of
the grille if necessary (picture 5). Ensure the screw
holes are aligned and fix the parts together using 2 x
TYPE OP04 screws.

fixing the parts together using 2 x TYPE OP05 screws.
Align the lug on the carburetor assembly
with the hole in the carburetor housing
and drop the assembly into the housing.
Fix in place using a TYPE OP03 screw.
Align the lugs and holes on the engine
block with the carburetor housing and fix
together using a TYPE OP03 screw.

ASSEMBLE THE EXHAUST PARTS
Align the notch on the exhaust collector with the exhaust
cylinder and tip assembly from stage 3. Push the parts
together firmly. Look at the end of the exhaust collector
– you will see holes are numbered 1–4. These holes
correspond with the numbers on the end of the exhaust
elbows. Attach the exhaust elbows by pushing them firmly
into the exhaust collector.
ADVICE FROM THE EXPERTS
Do not try to twist the exhaust pipes
in the holes as you’ll probably sheer off
the locating pin. You should pull them
out and re-insert them with the correct
alignment.
!
The flats with the number on (see picture 4) should
face each other for correct alignment. Once all four
pipes are firmly in place, hold the ends together
and align the four ends with the exhaust plate. This
is also engraved with the numbers 1–4 to assist with
correct alignment.
