REMOVAL:

 

Cars with Manual Steering – Disconnect the column coupler at the steering box. Remove the Pitman arm from the steering box and the relay rod. Remove the bolts holding the original steering box and remove it from the car.

 

Cars with Power Steering – Disconnect the column coupler at the steering box. Remove the Pitman arm from the steering box and the relay rod. Remove the bolts holding the original steering box and remove it from the car. Remove the factory ram assembly, control valve, and houses. (Once flushed clean, your original pump may be used.)

 

Steering Column Removal – Depending on the 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 the dash and floor. Disconnect the factory wiring from the column. Slide the column back and remove it from the car. The column will need to be modified to complete the installation.

 

INSTALLATION:

 

Note: A manual steering Relay-Rod or Drag Link Adapter will be required on cars with factory ram assist style power steering.

 

Note: Slight modifications are required to the original steering column.

 

1. 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. 1968-73 will require modification/relocation of the brake lines and brake proportioning valve for installation. Do not grind or alter the steering box.

 

2. 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 ¾ inches to that measurement to allow for steering shaft engagement in to the rag joint. Modify the column as follows:

 

3. 1963-66 Column Modification: 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 the rag joint if you are trimming the column shaft.

 

4. 1967-82 Column Modification: 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 too far; it can be difficult to get it back out.

Secure the column shaft with a set screw then a locknut.

 

4. Install the column tube over the shaft and reattach the column tube to the dash; the column tube will need to be shortened for clearance of the new steering box and rag joint.
