 Cars with power steering. Disconnect column coupler at steering box. Remove Pitman arm from steering box and
relay rod. Remove bolts holding original steering box and remove it from car. Remove factory ram assembly,
control valve, and hoses. (Once flushed clean your original pump may be used.)
 Steering column removal. Depending on available space and access to a lift you may want to remove your steering
column for ease of installation. Loosen or remove the bolts attaching the steering column to dash and floor.
Disconnect factory wiring from column. Slide column back and remove from the car. The column will need to be
modified to complete the installation. (Detailed Below)

INSTALLATION:
NOTE: Manual steering Relay-Rod or Drag Link Adapter #990002 will be required on cars with factory ram assist
style power steering.
NOTE: Slight modifications are required to original steering column. (Detailed Below)
 Bolt the new steering box to the frame. Check that the front of the steering box is not making contact with the
frame, or any surrounding brake lines. 1968-1973 Will require modification / relocation of brake lines and brake
proportioning valve for installation. Do not grind or alter the steering box.
 Connect the proper Rag Joint coupler to the new steering box. At this point the steering column shaft must be
shortened for a proper fit. Measure from the rag joint to the center of the hole on the steering column mount, add
3/4” to that measurement to allow for steering shaft engagement in to rag joint. Modify column as follows:
 1963-1966 Column modifications. Using the measurement from the rag joint to the column mount, measure
from the center of the mounting holes on the column to the end of the column shaft; subtract this measurement
from the one you obtained above. You will either need to trim the column shaft this amount or mount the column
further into the car. Be sure to leave enough spline for rag joint if trimming the column shaft.
 1967-1982 Column modifications. Using the measurement from the rag joint to the column mount, measure
from the center of the mounting holes on the column to the end of the column shaft; subtract this measurement
from the one you obtained above. You will need to gently tap the collapsible column shaft in to the column this
amount. Do not collapse the shaft to far; it can be difficult to get back out.
