Image #1: The original steering column protruded out the firewall about 3-1/2".

Image #2: The lower part of the column mast jacket originally attached to the firewall with a squeeze clamp that is bolted to the engine compartment side of the firewall with two 5/16" bolts. Remove the bolt at the top of the clamp and the two bolts that hold the clamp to the firewall and the clamp can be removed from the mast jacket.

Image #3: The top of the mast jacket attaches to the dash with a clamp that is held to the dash with two studs and nuts. To access the clamp, remove the lower mast jacket cover. The cover is held in place with a #8 sheet metal screw.

Image #4-5: The upper mast jacket cover snaps into the front of the instrument bezel. On automatic transm ission cars , an indicator wire PIN 57-130990-1runs from the shift tube to the shift indicator. This wire must be removed before removing the mast jacket. The indicator is spring loaded and the indicator wire simply hooks to the shift tube and indicator arm.

Image #6: Remove the two 1/2" nuts that hold the mast jacket to the dash clamp. The clamp will drop down and the mast jacket may be removed.

Image #7: The ididit tilt columns manufactured for the 1955-57 column shift cars have a ring on the shift tube so that the shift indicator wire can be reconnected. There is also a slot cut in the bottom of the column that will match up with the tab on the mast jacket to dash bracket.

Image #8: When the new tilt column is installed, the column should be flush with the firewall and not protrude as the original did. This allows clearance for a 605 or 670 power steering box or the new type rack and pinion coupler. With the tilt column flush with the firewall the stock mast jacket clamp will no longer work. PIN 57-140799-1 lower column mounting bracket mounts on the inside of the firewall using the two factory mounting nuts on the firewall.

Image #9: Rubber seal PIN 05-13 at the top of the steering column finishes off the column to instrument bezel area on 1955-56 cars. Slide the seal on from the bottom of the column.

Image #10: At the bottom of the steering column there is a foam rubber seal and rubber pad that seals the column to the firewall. The seals and pads are different between automatic and standard transmissions cars. The foam rubber seal PIN 57-131195-1 is the same for the 1955-57 automatic columns. The rubber pad for the 1955-56 automatic columns is PIN 57-130860-1.

Image #11: The stock upper mast jacket clamp will hold the new tilt column in place. Install the clamp, but leave it loose at this time.

Image #12: On 1955-56 cars there is a rubber strap PIN 57-130845-1 that wraps around the steering column. This holds the column tight in the upper mast jacket clamp. Slide the rubber down between the column and clamp, but leave the clamp loose.

Image #13: Slide the foam rubber column seal and rubber pad down over the lower column mounting bracket. The stem on the lower bracket sticks up through the center hole on the seals. The seal is held to the firewall with five plastic fasteners contained in P/N 57-135506-1. To install the fasteners use tool PIN 57-137036-1. This will push the fastener in straight and tight.

Image #14: Before tightening the upper and lower steering column clamps, adjust the steering column depth so that the loop on the shift tube lines up with the dash and the shift indicator wire P/N 57-130990-1 can be connected.

Image #15: With the indicator wire connected the upper steering column cover can be installed

Image #16: The lower column bracket PIN 53-104 includes a stainless band clamp. With the column adjusted properly, tighten the band clamp and upper mast jacket clamp

Image #17: The new tilt column includes a 1969-up tum signal switch. An adapter harness PIN 57-133752-1, 57-133753-1 or 57-133754-1 is available to connect the tilt column to the dash harness without doing any cutting or splicing.

Image #18: The new column and adapter harness includes a four­ way flasher. The red fused wire from the adapter harness should be connected to the "BAT" terminal on the ignition switch.

Image #19: The wires for the tum signal switch should be routed up the outside of the column on the left hand side. Once the wires are routed the lower mast jacket cover can be installed.

Image #20: The installed steering column is flush with the firewall giving you plenty of room for the coupler for a 605 or 670 power steering box.

Image #21: The steering columns will also work with the new rack and pinion shafts, so there is no longer a need to purchase a special column just for rack and pinion steering.

Image #22: The tilt steering columns come with billet knobs for the shifter, turn signal switch,tilt lever and the four way flasher.

Image #23: The replacement 15" steering wheels PIN 53-144 (1955-56), PIN 57-159996-1 (1957) or PIN 57-170911-1 (1959-60) can be installed on the new tilt steering column using kit PIN 57-160378-1. Your original wheel can be installed using the same adapter. Or, any aftermarket wheel may be used with no adapter.
