dash area. The tube will completely come off the shaft from the
inside of the vehicle. You may have to rotate the tube to clear the
firewall if column shift.
Gear box removal:
If switching to Rack & Pinion System:
Raise the front of the car with jack stands. Jack the car up about 1
foot; unbolt and remove the pitman arm. Unbolt the gearbox from
the frame. Unbolt the driver’s side motor mount from the frame
and jack the motor up just enough to slide the gearbox out. Once
the gearbox is removed the motor mount can be re-attached. (If
already using a Rack & Pinion system move on to pg 5)
If keeping the Stock Box:
Measure down from the dash mount locating tab and mark the
shaft at 21.5 inches. Then raise the front of the car on jack
stands about 1 foot. Un-bolt the pitman arm from the gearbox
and remove it. Unbolt the gearbox from the frame. You will have
to support the motor and unbolt the driver’s side motor mount
from the frame. Jack the motor just high enough to remove the
box. Once the box is removed the motor mount can then be
re-attached.
Gear box modifications:
The shaft of the gear box must now be cut to length and modified
to accept the DD Coupler. This is a round shaft with flats centered
on two sides. An easy way to do this is to make a paper template.
