INSTALLATION
Step 1.
Check tire pressure, take the car for a test drive and check the steering system
for defects and alignment. If everything is working correctly, continue with the
conversion.
Step 2.
Locate an ignition switched plus wire and label it. Disconnect the earth cable from
battery (also check if the car has a positive or negative earth). Align the front
wheels straight ahead and mark their position.
Step 3.
Remove the indicator light switch and
cut the wiring.

6
Step 4.
Remove both dash gauges to improve
accessibility.
Step 5.
Measure the distance from the steering
shaft to the dash. Make a note of this.

7
Step 6.
Remove the upper mounting bracket
from the original steering column
Step 7.
Remove the cover to get access to the
lower mounting points from the steering
column.

8
Step 8.
Remove the lower mounting bolts from
the original column (via the removed
cover). The bracket needs to be cut, so
that it can be removed completely. (see
photo for cutting line).
Step 9.
Cut the steering tube as low as possible.

9
Step 10.
Cut the steering shaft at the right length.
Measure the length from the power
steering columns, including the output
shaft. This length can be cut off from the
original shaft. (Caution: do not measure
the length from the piece which goes
into the steering shaft).
Step 11.
Loosen the nut from the steering box
which guides the wires internal. Push it
about 10cm through and cut this length
off (this is needed to fit the output shaft
inside the original steering shaft.

10
Step 12.
Fit the output shaft in the original
steering shaft. Weld it to the original
shaft.
CAUTION: the EZ output shaft is ready
to fit the original steering shaft. Once the
original steering shaft has been replaced,
it's possible that the EZ output shaft
doesn't fit. The standard internal
diameter for a replacement steering shaft
is normally 13.95mm. Check this and
adapt the EZ output shaft if needed.
Step 13.
Cut about 1cm out of the area at the
steering tube. It's marked red on the
photo. This is needed to give the clamp
enough clearance while mounting.
