A power steering pump will be needed. These require a mounting bracket, pulley, reservoir, and
hoses. Unisteer Performance Products offers a pump (see fig.2), call for pricing & ordering
details. The rack and pinion kit includes two #6 male AN fittings. This kit requires a mis-phasing of
the u-joints in the steering shaft. Smooth or splined shafting allows you to do this, but double D
shafts do not.
Removing Original Steering
(Please review the illustration to help understand terminology below)
1) Remove steering linkage
Remove nuts and cotter pins from the outer tie rod ends. Remove the outer tie rods from the
steering arms (a pickle fork may be needed). Unbolt the steering arms from the spindles, and
save the bolts. Unbolt idler arm. Remove the steering box nut below the pitman arm. Using a
puller remove the pitman arm. This will allow the entire stock steering linkage to be removed.
2) Remove steering box, and steering column
(This step is for cars with factory steering boxes, and columns)
Remove steering wheel nut, and steering wheel. The steering column shaft is part of the steering
box and cannot disconnect from the steering box. You may want to remove the existing headers
first to gain space. Unbolt the steering box from the frame and remove (pull down and forward).
When you remove the steering box, the column shaft will be removed as well. Set the entire
steering box assembly aside. Unbolt the column from the dash, and floor. Disconnect the
electrical connections from the column. Remove the steering column.
