We will work through this installation using all these parts. For instruction purposes
we will assume the car is all original and has a factory manual steering gear box
and an OEM harness. On the last page there will be a summary for optional Equip­ment, such as a rack and pinion or an aftermarket wiring harness. There will also be
instructions for OEM and aftermarket steering wheels.

REMOVAL of OEM Column:

Disconnect positive battery cable.

(Figure 1)

Under the dash disconnect two large plugs
from column, to under dash harness. NOTE,
if your car is equipped with a key light, there
may also a single small yellow wire that must
be disconnected. (See Figure 1)

Now you will have to drive out the roll pin in the
coupler on the gear box. We soaked the pin with
penetrating oil and that didn’t help much. I ended
up drilling out the pin with a carbide drill. (drill size­5/16 ) (See Figure 2B)

If this car is a 1970 or has column shift, there is a
linkage at the bottom of the column. This linkage
must be disconnected from column. There should
be a cotter pin and a washer. If your vehicle is a

1970 model, and is a oor shift, remove this linkage

completely it will not be reused. (See Figure 2A)

Remove the three bolts that hold the mount to the

re wall, and the two that hold the load plate to

the mount. (See Figure 3)

Now you can remove the two nuts and washers
that hold the column to the dash. Note this will re­lease the column from all mounts and it will want
to fall. After the column is loose you will have to

rotate and watch the re wall mount plate to get

it past the pedals. (See Figure 4)

INSTALLATION:

The rewall mount is rst, loosen and remove the load plate and o-ring. Install re­wall gasket and plate loosely with the bolts and washers provided. Install the plate

with the lip facing the engine side of the rewall. (See Figure 6)

Tip…To do a professional job you

may want to put a layer of masking tape
on the steering column from the tabs
down. The next part of the installation

could scuff the nish on the column.

Column Preparation

Slide the load plate onto the column with the raised lip facing the wheel side of the
column. Then slip the O-ring against the load plate. This will hold the load plate out
of the way while sliding the column in. Locate the 2 nuts and washers provided with
the kit for the dash mount. If you haven’t checked this out yet… pull the lower shaft of
the column out about 2 inches, and then push it back rapidly with your hand. This will

make the column at its shortest point, and will give you the most possible clearance

while sliding through the rewall.

Now with one hand in the middle of the col­umn and one at the top, slide the column be-

tween the pedals and threw the hole in the oor

mount. Set the column against the dash mount
studs and center the studs in the slot provided.
Loosely install the washers and nuts onto the
studs. You should note that the studs and the
slots allow for adjustment of the column from
left to right and front to back. Center the col­umn from front to back and adjust left to right
until the column is centered in the plastic dash
housings as close as possible. Then lightly
tighten bolts. (See Figure 7)

(Figure 6)

(Figure 7)

Next slide the load plate of the rewall mount

down the column till it is against the plate. In­stall the two bolts and washers and tighten to
11 FT. LBS. (See Figure 8)
