Electrical power steering (EPAS) on a 1965 Falcon


Putting an electrically power asisted steering (EPAS) on a classic car is not a new idea, but it may work really well for me.

Step 1. Get a 2005 saturn or vue electric power steering module, be sure to get every rod and connection attached to it, it will be used later.

Step 2. 

Get a 1965 Mustang steering column because this conversion requires to cut the column, it is a lot easyer to cut a Mustang one without a column shift that one from a Falcon, unfortunately this conversion requires to drop the column shifter, so you must find the way  to put a floor shifter. I will put a 4 speed toploader but this is a subjet for another entry.

Optionally you may get a falcon column and steering box, if you need to go back to he original setup you will be able to.

On this picture, from top to bottom: 65 Mustang column, Falcon shifter column and in the lower row is the EPAS, mechanical connections from the donor car and a Falcon steering box with a cutted input shaft.

Step 3.

If your car has a long input shaft steering box, you will find that there is no oil seal at the input shaft and the lower end from the steering column has a rubber seal to protect the internal parts at the steering box. Because I will use a slightly different column from a 65 mustang, there will be no seal at the input shaft.

First, cut the input shaft about 3 inches from the steering box enclosure, now it is a good time to rebuild the steering box, this is a good tutorial on how to do it.


With a fully disassembled steering box, take the brearing adjuster to the machine shop and make two modifications, cut the input shaft nozzle and cut a “box" for the new oil seal, a good option for this application is 3/4"x1-1/4” IMPORTANT NOTE. Make sure to take the bearing race center, otherwise the oil seal will no be propperly aligned with the input shaft.

After. Bearing adjuster with a new oil seal.

Second. Take the input shaft and make a double D connection for the connection hardware.

Keep the connection as close as possible, an adjustable connection rod is a great advantage.

Replace al bearings fro the steering box and reassemble.
