When using an aftermarket tilt column along with an updated steering system, it's necessary to eliminate the stock (ugly) lower steering column clamp. There are several ways to mount the column; one is inexpensive while the other is more attractive and gives your under-hood area a real custom look. This article will show you how to install either type of lower column mounting system.

Image 1: When installing an aftermarket steering column in a 1955-57 Chevy, the column mounts flush with the firewall. This is to allow for clearance on the engine compartment side for all types of steering boxes and rack and pinion conversions.
Image 2: Classic Chevy has a simple bracket and clamp (PIN 57-140799-1) that mounts on the inside of the firewall and uses a 2" band clamp that holds the lower steering column in place. This cleans up the firewall and gives room for any type of steering conversion and will work with the stock lower column foam seal and rubber.
Image 3: A new custom stainless steel mounting bracket has been developed to do the same job as the PIN 57-140799-1 mounting bracket but eliminates the use of the stock foam seal and will give a clean and custom look to the firewall.
Image 4: The stainless mounting bracket PIN 57-164270-1 is for a car with a manual transmission and includes the hole for the clutch. We are installing the bracket PIN 57-164268-1 for an automatic transmission which will cover the hole in the firewall for the clutch rod. The new bracket bolts to the outside of the firewall using the two original nuts spot welded to the toe board. The new bracket includes two stainless steel button head bolts and washers to attach the bracket to the firewall. The mounting holes are slotted for adjustability.
Image 5: The firewall side of the bracket is highly polished and when installed gives the firewall a real custom look.
Image 6: The 2" band clamp wraps around the bottom of the steering column and secures the tab on the stainless steel bracket tight to the steering column. The original inner rubber floor seal PIN 57-130860-1 covers the new bracket on the inside. On 1956-57 cars, fasteners PIN 57-135506-1 secures the floor seal to the firewall. The 1955 cars use fasteners PIN 57-135375-1. The original lower center fastener for the rubber will no longer be used.
