1971 Ford Mustang Mach 1 Power Steering Conversion


Recommended Posts

So after 30 plus years of ownership and just plain tired of muscling this muscle car, I made the decision to convert my manual steering Mach 1 to power steering. The car is a base Mach with a 351, manual brakes and a 4 speed, no AC 


I looked at several options, from converting to electric (discarded this idea as I would have had to cut the steering column and the cost would have been over $1,500), using a Borgeson unit (discounted this due to some feedback on possible fitment issues) - which in the end, left me with sourcing an OE set up. 


After a month or so of research, I was able to source all of the parts needed. While not a cheap conversion and hours of preparation, sandblasting and painting, I am glad I made the change. For those that may be interested in making such a change, I’ve listed the parts needed and my sources. One suggestion - when sourcing crank and water pump pulleys, be sure to get them from the same car, or ensure that you get the correct cast date numbers.

Back in the day, I wouldn't consider having a vehicle with power steering or air conditioning. Now I wouldn't do without it. Even have to have power windows, now-a-days, which my Mustang doesn't have. Something else to add to the want-to-do (dream) list.


Good job getting it installed, amazing how many parts it takes for something that doesn't seem that it would be difficult.
